This issue was fixed in systemd by
https://github.com/systemd/systemd/pull/15318. Debian cherry-picked that
change into 245.4-3, so Debian bullseye and buster-backports have the
fix, as does Ubuntu 20.04 (focal).

First message in second seat greeter log file is logged after less
than 1 second when I log in in first seat. At this moment greeter
starts eating cpu.
Please attach a debugger and get a stack trace when this happens.
Does the greeter crash, exit, or move to the background?
Greeter

Sounds to me like there's a bug in your udev rules. Does:

* You don't need a udev rule to assign something to seat0.
Everything is assigned to seat0 by default.
* Probably unrelated
