[Vanilla] Play by Cloud: Error Starting Game

[dru-13]

I tried the Play by Cloud mode and played a few rounds successfully before I got the error message 'Error Starting Game: There was an error starting the game. We recommend disabling any mods and trying again. error- Save version is incompatible.' Nobody in the game uses any mods, both of us were in game at the time so I don't see how any settings or anything can change, I've uninstalled and reinstalled, I talked with 2K Support and tried everything they recommended. I can't play this save and I can't delete it, which means every time I open Steam, I get a notification saying it's my turn. Has anyone run into this or have any solutions? Either for fixing the save or deleting it.
