Hi, is there a crash log?
https://forum.unity.com/threads/where-to-find-the-crash-log.779012/
It says here you can find it in the AppData folder :O
'Immediately after the Unity Editor crashes, if you open the Editor log file, you'll see a line explaining where the crash information was stored. I think mine tend to end up in C:\Users\Dan\AppData\LocalLow\Unity'
I've never experienced the crash so I can't replicate it, but this would give me more information to fix it!
