Hello,
What exact error message do you receive when you open Microsoft apps on your Windows PC after installing the latest updates?
In the meantime, I recommend uninstalling and reinstalling Microsoft Edge WebView2 Runtime, as these apps are WebView2-based. Reinstalling it might resolve the issue.
To uninstall,
Open CMD (ADMIN)
run these commands one by one.
cd C:\Program Files (x86)\Microsoft\EdgeWebView\Application\1*\Installer
setup.exe --uninstall --msedgewebview --system-level --verbose-logging --force-uninstall
Reinstall
Microsoft Edge WebView2 from this link.
Download (Evergreen Bootstrapper)
Once installed, restart your PC and open these applications.
