Additional Context

I recently installed Win10 and then upgraded to Win11. After that I installed ModernFlyouts via chocolatey, worked perfectly. At some point I switched to winget and installed it there instead (I don't remember the reason, probably more recent version).

At this point the app did not work anymore, as described above. I installing it from chocolatey again, I got an error message for missing permissions. It seemed ModernFlyouts was uninstalled incorrectly, because there were multiple folders in C:\Program Files\WindowsApps that only contained a AppxManifest.xml file. But installation from the Windows store worked, the program still had the same issue though.

Before posting a bug report I tried to find out more about the problem. sfc /scannow and then dism /online /cleanup-image /restorehealth fixed the permission error in winget and chocolatey. Get-AppxLog doesn't seem to show anything pointing to the error.

I know this is a very vague issue, but as I don't have much experience with Appx packages, I don't know how to find the relevant logs or error messages.
