The last update to Big Sur seems to have randomly revoked different permissions for various apps. Open System Preferences and go to Security & Privacy. Open the Privacy tab.

Check the different categories and see if Keyboard Maestro and Keyboard Maestro Engine are listed, but the checkbox is off. Turn those options back on (assuming you want Keyboard Maestro to have that permission).

See the post for full details.
