I couldn't reproduce, on 2nd attempt to host the game, it worked fine, so probably no serious issue. But if the error occurs again, I'll try to keep the popup screenshot as well. Thank you for checking it

I was hosting a space age dlc game, when my friend was joining. I paused to game to make it a bit faster for him to join. Then I got a crash with an error popup.
I somehow misplaced the screenshot of the popup unfortunately.
But I have saved the logs and the crashdump (see attached zip file)
