Universal app crashing at site only when connected to internet

Hello,

I have a Windows Universal app that runs well at a few locations. At one location, I can start the app if the PC is disconnected from the internet. as soon as it is connected to the internet, the app will crash as soon as I start it.

the event logger shows: Faulting module path: C:\Windows\System32\Windows.UI.Xaml.dll

What I have tried:

I have tried sending a webcall in a browser, and I get back the result I was expecting.

I made a special build where I took out any calls the would access network or internet and it still crashes even before creating my main page

We have tried 2 units at this client that works when I tested it in my office, but at the client they don't work.

At the client we also tried using different internet connections (wifi and lan) and 2 different ISPs and still no luck.

Any ideas on what could cause something like this?

Thanks.

Side-loaded? App store? Trying to get to app store?

This is a sideloaded app that I created. certificate installed, dependencies installed. As mentioned, it works on a few other devices with no issues. At this client, I sent them 2 different units that worked when I tested them in my office, but when they connected it at the client, the app will not even start, it crashed even before it has any calls to the internet. The strange thing is that if it is not connected to the internet, the app will start (obviously cannot connect to the server) - but when it is connected to the internet it will crash. Simply strange and I cannot even get it to write a debug line in a txt file at the beginning of app.xaml.cs.
