Even with redownloading mounted I get this error

Traceback (most recent call last):

Are you running the MountEFI.command from within its original folder? It needs to be in the same directory as the Scripts folder, which should contain __init__.py, bdmesg.py, disk.py, etc. If you've copied the MountEFI.command somewhere else, and it can no longer reach those scripts, it will not work properly.

Alternatively - are you launching it via the terminal? If so - make sure you first cd into MountEFI.command's directory, then try running ./MountEFI.command

This error occurred to me as well. I'm on macOS 12.0.1 and i hadn't seen it before on macOS 11.
The fix was to move the Mount-EFI folder to some other place like macOS's root directory. I tried it with it being in the Desktop and the Downloads folder and those didn't work.
