I updated my Mi 11 Pro to Android 12 Beta 21.10.22 yesterday and everything (except for my fail with Magisk) worked fine. But today my phone started to reboot randomly. I can only unlock my sim and use my pattern to unlock the phone before it crashes and reboots. Maybe a Magisk module or Magisk in general causes the crash, so I flashed the original boot.img. Still crashes. After removing my theme (because I read the update logs that using Themes might not work) it still crashes. Maybe this is the wrong section but In case my logfiles:
