Ok I am experiencing the same issue. I think I know what the issue is.
If you are using Windows 7, and if you go to your Edit your environment variables and added
C:\Program Files\MongoDB\Server\4.2\bin, this will install your shell path.
But if you installed Mongo Compass DB it will just keep trying to activate plugins unless you change your environment variable to C:\Windows\System32\Wbem. But now you cant access your shell path.
So you have to create two paths. But the problem I am having now is what to name the shell path?
