With the Orange Pi Zero 2 (Bullseye), when in Armbian-config I install desktop with browser...it seems working but when you enable the desktop it finished by a kill() in the terminal.
You can solve the issue by apt-get install tightdm.after and not before.
You will get the desktop for the user and not root. Grey Background with the pinguin.
If you install Desktop in Bullseye with Orange Pi One Plus or Orange Pi Zero, no issue. You have the new Debian Desktop with a Background dark blue.
