I had a brief look at this using the latest daily build ISO for Ubuntu MATE 21.04.

lightdm has code for disabling the MATE screensaver. I confirmed that it works by opening a terminal window within a guest session:

$ gsettings get org.mate.screensaver lock-enabled
false

But I could still reproduce the issue, i.e. I switched to my regular user and then when trying to switch back to the guest session it prompted me for the non-existing password.

We should keep in mind that the guest session feature is deprecated and disabled by default:

AFAIK nobody makes any effort any longer to make sure it keeps working when software is upgraded.
