When I shutdown or restart my Mac mini 2018 running macOS Monterey, for half a second a window appears, saying that Enpass interrupted my Mac from shutdown/restart. Then the window disappears by itself, and my Mac shuts down/restarts. How can I solve this issue?

That warning is from the OS itself. During shutdown the OS sends a quit request to all open apps. If the app doesn’t respond immediately or shut down, the OS shows that notification. If the app quits in the meantime, the notice automatically goes away. Enpass just takes slightly longer to shut down than the OS is configured to wait. You can safely ignore that unless Enpass is actually stopping your machine from shutting down or restarting. 

Thank you for the explanation.
