WebView2 freezes on copy/paste in C# app. WindowsAppSDK 1.2 regression?

[DierkDroth]

Hi,

I'm using WebView2 in a C# .NET7 + latest WindowsAppSDK app.

Since most recent updates to WindowsAPPSDK 1.2 the WebView2 component freezes randomly. Although I can't really put my finger on it and can't provide a repo, I noticed that this is around copy/paste:

• I saw it on copy/paste to some HTML controls
• I'm also getting it on copy/paste on a HTML document where was 'contenteditable=true'

The application main thread appears to be completely frozen. I didn't see anything sticking out in debugger (neither managed nor unmanaged code).

I don't think I have seen it with WindowsAppSDK 1.1.X and before. Hence, I have to believe this is a regression in WindowsAppSDK 1.2.X.

Any idea what might be causing that?
Thanks in advance
