[Problem/Bug]: Some websites (LinkedIn, Facebook, Twitter) cause a crash of the WebView CoreWebView2 instance

[mkumar12345]

What happened?

This has started happening for the past few days, so after the WebView2 120.0.2210.121, .Net Framework 4.8 update.

If you try to navigate to linkedin.com, facebook.com, or twitter.com the corewebview2 instance crashes and you see an empty panel where the webview2 was.

Other websites I have tested like google, bing, work fine. Seems to be limited to social media websites listed. Although instagram.com loads fine.

Hi, @mkumar12345!

It seems that your issue contains the word "crash". If you have not already, could you attach a crash dump as a comment?

WV2 crash dumps are located in a subfolder of the app's user data folder (UDF): <UDF>\EBWebView\Crashpad\reports\. By default, the user data folder is created in the app's folder with a name like <App Exe Name>.exe.WebView2. Refer to Crash Diagnostics for more information.

Thank you for your cooperation!
