- Maui Version.
- What is your system version? Someone mentioned the issue of program crash after updating in the After updating Windows 10, Windows can no longer manage any appx packages, and I can't deploy WinUI 3 apps from VS #4881. There is a workaround for this using the command line. Does it help your situation?
Your prompt reply will be highly appreciated.
