While I was hoping 50.05 of the premium release would resolve my CTD on loading certain saves, it seems I'm out of luck. This has effected both manual saves and autosaves over the course of several months. While I have mods installed through the Steam Workshop, I don't have any enabled in this save. Just in case they were the problem regardless, I removed them all and saw the same error in the error log. I've also ensured my game is up-to-date and validated my files.

After crashing, the error log says:
