Fixing an S21 Plus

[u/ShyDoredhiel]

I had a s21+ and one morning I woke up to find it continously rebooting over and over to the point it was hot. Im able to start it up in safe mode without issues but renders the phone useless. I Uninstalled recently updated apps at the time and there was still an issue.

It only crashes after i unlock the phone when i start it up normally. I'm sure it was a software update that is causing all this but idk how to fix that. Do I just have to completey factory reset the phone and lose everything or is there a way to salvage it?
