I am getting this problem as of this month's update. I have latest edge and webview2 runtime.
Hi Umbs:
I made an interesting discovery after reading your 14-Nov-2024 post. The Microsoft Edge WebView2 Runtime has disappeared from both Control Panel | Programs | Programs and Features and Settings | Apps | Apps and Features on my Win 10 v22H2 machine since my MS Edge browser updated to v131.0.2903.48 yesterday on 14-Nov-2024.
See my 14-Nov-2024 post # 2717543 in Susan Bradly's 14-Oct-2024 topic Are You Ready for Windows 11 24H2? in the AskWoody forum (I post there as user lmacri) where others are now reporting similar oddities with Microsoft Edge WebView2 Runtime. There's a long discussion in that topic about the News and Interests process in Task Manager, and at the moment no one knows if this disappearance of Microsoft Edge WebView2 Runtime is caused by a bug in MS Edge v131.0.2903.48 or if it's a deliberate feature change by Microsoft.
As I noted in post # 2717624 of that Askwoody topic, I happened to run a winget list --name WebView2 command in an elevated command prompt two weeks ago on 29-Oct-2024 and it detected Microsoft Edge WebView2 Runtime v130.0.2849.56 ...

... and today that same command returns "No installed package found matching criteria" .
