I am stuck at turn 53 into the dwarven campaign. All saves that are created after the current turn wont be loaded anymore. While loading old save games still works...
1. ...loading newly created save games (local or cloud) just drops me back into the menu without any error message
2. ...starting from the laucher with "continue campaign" just crashes the program completely

What could be the issue here? And what are my options to fix it?

I have enabled all free DLCs available on steam and am not using any mods (eventough the the build number in the menu screen states "(modded)")
