[2023] Having Frequent Soft Crashes in 1.35.*

Was this in a campaign started under the new patches 1.35.x ? If under an older patch, you'll need to revert to that version in the Steam betas tab for the game, to continue it.  

Did you see this question?

Maybe attach a problem save file here to see if we get the same problem.
