'How do I fix the Ubuntu 20 startup error "[FAILED] Failed to start Forward Password Requests to Wall Directory Watch"?

When I booted up the Ubuntu 20.04, there was an error "[FAILED] Failed to start Forward Password Requests to Wall Directory Watch" and many others error (shown in the image), and the computer got stuck and rebooted after a while. I'm trying to fix the error, but it doesn't work. Could anyone help me? The startup errors of Ubuntu 20.4
