Probably because of the "overhead" of your app and any memory restrictions.

The WebBrowser control is stuck in IE7 mode (unless you mess around with the registry on every computer where your application runs):
Web Browser Control & Specifying the IE Version - Rick Strahl's Web Log[^]

And even Microsoft will tell you that Internet Explorer is a "compatibility solution", not a web browser:
Microsoft security chief: IE is not a browser, so stop using it as your default | ZDNet[^]

You should switch to using a better browser control - for example:
CefSharp - Fast web browser for WinForms and WPF Apps[^]
Microsoft Edge WebView2 Control - Microsoft Edge Development | Microsoft Docs[^]
