I just reported https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1969250 which was marked as duplicate of this bug (which it is), but do check that bug for a bit more analysis on where the bug is. TL;DR: there are nvidia-specific checks in 61-gdm.rules that are no longer guarded by a check for nvidia hardware in the rules file (because the patch reversal in 42.0-1ubuntu4 removed that check).

As a workaround, you can edit /lib/udev/rules.d/61-gdm.rules and comment out or remove these lines:
