Webview2 doesn't work after last Edge update

What happened?

I am finding a bug with WebView2 and Edge. And I'm not the only one. There is another user who started the help ticket.
BUG Webwies2 search works outside of App container

This person knows more than me. I just know what works and doesn't work. I'm getting tired of not being able to play my games.

I found 3 WebView2 files on my computer - 3/21/24, 11/11/25 and 12/9/25. And I have not found any file labelled WebView runtime

Edge 143.0.3650.96 was updated on 12/19/25 (released 12/18/25).

On Thursday 12/18 everything worked just fine when I cut my laptop off to go to bed.

On Friday morning 12/19, Edge downloaded new update. After that, my widgets don't work, WhatsApp doesn't work right, and I can't get any of my G5 games to work.

I don't think the WebView2 is broken, I think the problems are caused by the Edge update. But I don't know why or how. There must be some code in Edge that causes these problems.

Importance

Blocking. My app's basic functions are not working due to this issue.
