I've had the same error only a few months later. My gamestate as the soviet union always crashed on the 2nd october 1941. I've looked up thr forums and so on and unfortunately i don't think theres a way to fix that problem. Most bice games crash in 1941 or early 1942

What DLCs are you guys using?

I'm getting crashes since today, never had them before.
I own every DLC.

Crashing around 7-10 October 1939 and cant get beyond it. Playing as Italy, no other mods & running the correct version of the game. If I save moments before the last crash I can load the game and play another additional 24 hours then it crashes again. Managed to nudge the game along a few days doing this but its not playable like this and cant seem to push the game beyond the catalyst of....whatever is causing the crash

Also using all DLCs

Same here I'm using all DLCs and I crash at the same time

The last crash issue was supposedly fixed in the last update. Steam is weird nowadats tho so make sure you get the latest
