My first thought is a memory issue; how much RAM do you have? Unity is sometimes finicky with low-memory systems.
Regardless, I'll look into this. Thank you for reporting the crashes, and sorry you've had issues!
I think you were right about it being a memory issue! I have 8GB of RAM, but figured out there was a bunch of stuff running in the background. I just played for an hour without any crashes. Thanks for the help!
