My 2018 MBP died badly with the beta, all I got was the notification that the beta was available I clicked on it, computer rebooted then installed, logged in once then it crashed, I never got in again, safe mode did not help (did not work), I then tried to recover my time machine backups that failed as it put ventura back on even though the backups were from a couple of days before. I deleted the partitions tried the recovery that failed too. only thing that worked was the internet recovery console, CTRL-OPT-CMD-R, installed the MacOS from when the MBP was new so it installed High Sierra, I then upgraded it to Monterey, then I used the time machine to recover the files, that worked.
I would not say this build was beta quality, more like alpha quality given ease at which it crashed.
Make sure you have good backups before putting this beta on, I lost 24 hours of my life on this mess.
