I want to make it extra clear that this is Googles beta. Not ours. What CH_ASUS says above is that some stuff won't work. Which you can clearly see here
https://www.asus.com/content/android-12-beta/Known issues
Fingerprint authentication currently not supported
Face unlock feature currently not supported
No haptic feedback when touching the recent key
Battery status displayed in Settings may be inaccurate
3rd-party apps compatibility issues
It's only when Android 12 with ZenUI beta starts that we will start fixing everything that's not working.
You should only install the current A12 beta if you're curious about Android 12 or if you're a developer.
It's not optimal for normal users to install A12 if this is your only device
