I have an issue with Edge and the Start Menu on Windows 10 1809
Edge does not accept copy and paste commands. I was able to get the keyboard input working by running ctfmon manually
The same rings true for the Start Menu, even doing a right click and running the selection yields errors, Powershell link does not work.
Windows Start menu exhibits the same issues
I have done the following
Get-AppXPackage fix, the Dism restorehealth as well as sfc none of which has fixed the issue
