I have an issue with Quick Assist and Windows 11 Version 10.0.22000.675, OS is joined to a domain

Quick Assist has been correctly updated through Windows Store, but as soon it starts suddenly disappears

checking event viewer I see that application crash, see below details
I can also state:
Microsoft EDGE is updated
tried to reinstall WebViewer2 but it says that is already installed
uninstall and reinstall quick assist won't solve the issue

all repairing modes tried doesn't work, scan SFC or health image, along workaround with PowerShell re-instate
Get-AppXPackage | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

it looks like that its related to EmbeddedBrowserWebView.dll but is totally out of blue to me

is anyone able to help ?
thanks a lot

got solved this issue

first of all, is totally related to WebViewer2 runtime which is part of Microsoft EDGE
in-fact embeddedbrowserwebview.dll is the application that fails, due it is called/used by quickassist.exe

1) I had to remove and reinstall afterwards .NET 2.0, 3.0 and .NET 4.8 Advanced Services
2) I had to uninstall WebViewer2 runtime with Bulk Crap help, using disable protection feature, it is a Microsoft app with no uninstall feature
3) whilst I was usning Bulk Crap, I also uninstalled Quick Assist along its leftovers within same tool
4) restarts as well included though

5) I had to manually re-install WebView runtime

6) Installed as last piece Quick Assist from Windows Store and finally worked
however, I'm not convinced that this check-list upon is the correct fixing, I'm still convinced that root cause of this is (was) a "pending update" status, I have to remark that this machine is joined to a domain with also updates under GPO control, even though a manual update is also enabled whenever it needs

I do not have another machine on where I could reproduce the same issue, but I'm pretty confident that instead of this checklist, a forcing windows update would have been solved the issue

any thoughts from your side ?
