We had the same issue with some systems after the Almalinux 8.4 > 8.5 update.

Solved by switching to Gnome then back to MATE.

I've done a bit of experimenting with a few other computers and found that if I switch to lightdm first, then upgrade to Centos 8.5 everything works just fine and as expected. If I upgrade to 8.5 first and reboot while still using gdm I can't log back in with Mate and though I can still log in with Gnome.

I think the easiest course of action here is to install and activate lightdm first, then do the upgrade to 8.5. Everything just works.
