Solved
I updated my game today with the new November 2020 update. It let me play for a little while (10-20) minutes before crashing. Nothing popped up on my screen and no error code either. The game just closed itself basically. I play on Mac.
Edit - edited title to reflect issue since the 10 November patch, 1.68. (Bluebellflora)
Fixed in the 17.11.20 hot fix patch 1.68.156.1220
