Hello! Sorry to see you’ve been having such a difficult time.
These crashes are all deadlocks, which can be particularly tricky to pin down. However, there is a correlation between Ryzen 5 CPUs and frequent crashing, and AMD have confirmed that updating the BIOS can resolve that. If you wouldn’t mind, could you please try performing a BIOS update? Please see the motherboard manufacturer’s website for instructions on how to do this.
I’ve asked our engine developers to take a look at your crashes. Until then, hopefully a BIOS update is all it will take to get this sorted. Keep us posted on your situation!
