I found a similar issue and you can refer to the steps and the reference blog in it.
You can get Edge full package name using PowerShell:
Get-AppxPackage | Where-Object {$_.Name -like "*MicrosoftEdge*"}
Add the full package name as a key to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Appx\AppxAllUserStore\Applications
Then create a string name = Path
, value= C:\Program Files\WindowsApps\packagename\AppxManifest.xml
in that key. Please note to change the packagename to your owns.
I also found this link about registering AppX applications, you can also refer to it.
