I am not trying to ignite an old war, I prefer Desktop App dev, but the wave caught me, doing web dev now, and at peace with it (sort of)...
But as I was looking at our app, it suddenly struck me... however bad is your javascript, html, server code, seldom will the browser freeze. Maybe the page will be stuck loading but you can close it, ignore it, open another tab...
However, if you write ugly bad desktop code, with humongous calculation in your UI thread, your app can easily freeze. For example I wouldn't trust one of the developer here where I am to work with me on any app... this guy... makes me sad..
[EDIT] To summarise the point above concisely: An awful web app coded by stupid developers will fail more gracefully than an awful desktop app coded by other stupid developer!
Anyway, it even happen to me, I often read multiple PDFs at home with Foxit, and I noticed lately Foxit tend to freeze easily. The whole application freeze, can't even navigate to another PDF / tab, this is annoying... 
--
Which makes me think... Any PDF reader recommendation?
[EDIT]
Just checked Adobe Acrobat Reader, it's better that it used to be, might use that! 
But Foxit has an easy edit of Bookmarks, still great for that!

Browsers these days do a pretty good job rendering PDFs. At least the Chromium-based ones. (My default for PDF is Brave on Ubuntu.) But then I don't have a need to bookmark pages within PDFs...

Browser is barely sufficient..
Yes it renders but it's unusable... I do need the bookmark pane on the side permanently open and pointing to my current location... Those PDF I am using have like 200~400 pages...

Yes but... do you have multiple 400 pages PDF that you let open in the background for a while and check every now and then?!
Because I also have 16GB and 8 cores! 
In fact I regret it, should have installed 32GB

Maybe one of these: pdf-viewers-for-windows[^]
I always used the Edge browser as it could also read ePub files, and guess what?
Since the last update that functionality has been lost

Yep, that annoyed me as well - the one thing Edge did well, and they removed it ...

I use Corel PDF Fusion (reader and writer), but mostly because it's less annoying the Adobe and it came free with one or other of the Paintshop Pro upgrades I have bought over the years.
It works, but it's not free (they do a free trial though if you want to try it out.)

Having worked on desktop, mobile and web apps I can see the attraction of desktop apps.
I think perhaps the biggest advantage I have found if the stability and slowness of 'innovation' on the desktop side.
It means that you can get quite skilled at working in a particular framework or area and make more stable applications.
My experience with mobile and web applications is that the modern response to most problems is "there's an npm/git package/library solution for that" and before you know it you are battling with side-effects and problems introduced by that "solution".
But from a programming point of view there is not too much different between the three platforms - the difference that is probably most prominent is having to understand areas like security and 'defensive programming' when doing web and mobile development.

Well that was my point!
An awful web app coded by stupid developers will be less painful than an awful desktop app coded by other stupid developer!

The apparent advantage of web apps (where crashes are concerned) is because the client side of the app is interpreted, not compiled. All this means is that the interpreter was written properly, and allows breaking at (almost) any point.
The server side can still be written so as to crash, perform long calculations in the servicing thread(s), and all other things that we know and "love".
Freedom is the freedom to say that two plus two make four. If that is granted, all else follows.

I had those same problems with Adobe Acrobat Reader.
After I installed a new version (or just reinstall?) it works fine again though.
I usually use Chrome or Edge to read PDF though.
One of the things I love about web development is that it's way easier to deploy.
You don't need to deploy secrets to users, no copy/pasting files for every user (they can't use installers), no VPN connections (unless the app is hosted on-premises) and you're sure everybody is on the latest version!

I installed the latest version of Adobe Acrobat Reader (which I didn't installed for many years now) opened 4 PDF documents, 300 pages each, went to play some Assassin Creed Odyssey for a while...
And now I am back on the desktop, clicked on Acrobat Reader, clicked some bookmarks, boom, instant response!
I like it!

So what you're saying is that you can pretty much get away with writing crap code without trashing the user's machine...
Web dev is actually harder than desktop dev.
0) There are FIVE languages associated with most (ASP.NET) web sites:
- HTML
- CSS
- C#
- Javascript
- SQL
1) CSS is probably the hardest thing to get right. You have to be careful selecting 3rd party libs because of possible incompatibilities.
2) Javascript is the same everywhere, but selecting a framework is a nightmare, simply because of the sheer dirth of options.
3) SQL presents its own challenges because writing a query is kinda like writing code backwards.
4) Deployment can be a minor nightmare if you store connection strings in the web config file, and you have to "deploy" to different environments in the course of preparing code for production.
5) Web dev is stateless, and unless steps are taken, variables are not persistent between requests.
6) You have to be cognizant of memory consumption, especially on a website that gets a lot of traffic.
With desktop apps, you have few if any of those considerations.

Yeah, instead of crashing the user's machine, you can take down an entire server.

Any particular web app won't necessarily trash the user's machine, but a browser on its own most certainly is more than capable.
Fire up any browser today and watch memory usage go up. You don't even have to load a page. I just launched Chrome on a freshly rebooted Win7 machine - 8 instances of chrome.exe showed up, chewing up at least 120MB of RAM - it hasn't even loaded a page; I always default to a blank one. Firefox launched 5 instances; one of them used up 245MB of RAM, then slowly backed down to 165. Edge (the Chromium-based one) also launched 8 instances, eating up at least 120MB. Any Chromium-based browser (and most of them today are) should show similar results.
I have a number of old laptops. I like taking one of them out in the backyard and browser for a while. With 4GB of RAM or less, this is getting into an exercise in frustration--it's constantly paging. I have older relatives with a system with 2GB of RAM - I don't know how they tolerate it. A friend-of-a-friend showed up recently with a "dead-slow" laptop with 8GB of RAM. I was appalled at its performance; it was constantly paging because...all the memory was going to the browser.
So while browsers themselves are heavily threaded and you hardly ever see a browser's main window turning white and its caption saying "unresponsive", you now kinda have to guess as to whether anything is ever going to spring back to life, as click events can take a long time to register and do anything in response.
And none of this is something the average web developer can do anything about. Have we really solved anything? "Throw more hardware at it" is such a cop-out.

SumatraPDF. Looks old, performs really well. Fast to start, does all I need from a PDF (and CBZ and MOBI and EPUB and ...) reader.

Concurrency's still not easy enough for a lot of desktop developers, even with things like tasks in C#, futures in C++ etc. I think the Qt integration of concurrency & GUI programming is the easiest one I've used, with their QFutureWatcher class, which fires off a GUI event when a concurrent task (packaged in a QFuture) completes.

I find async so easy and convenient!
But yea, I have met many developer who, for some reason, are very slow on the uptake.. almost like they don't want to do it, and don't understand the benefits and don't understand where it is actually useful...

+1 for Sumatra. I've hated Adobe Reader with a passion from the get-go, put up with FoxIt until it became bloatware (why does a PDF reader need a plugin for Facebook, and why do I have to re-disable it every time I download an update?), and couldn't be happier with Sumatra. It does exactly what a PDF reader should do, and doesn't even pretend to try to do anything more than that.
It's rather ugly, but then you'd supposed to focus on the PDF content, so who cares about the menus around it.
