If you manually deleted WpcMon.exe from your PC, go to another PC that has Windows 11 installed, then open File Explorer and go to C:\Windows\System32
Find WpcMon.exe and copy it out to a USB flash drive.
Then copy that file into the same folder (C:\Windows\System32) on your device and restart Windows.
If that does not resolve the problem, then resetting Windows may be the only option remaining.
