I am unable to play beyond 1850,

Hello, thank you for your report! Unfortunately, the information you've provided is not sufficient for us to determine what's going on.
Could you:
- attach a save where the game crashes; and
- attach a zipped crash folder (which can be found in \Documents\Paradox Interactive\Victoria 3\crashes folder)?
This would make it much easier for us to both figure out what's going on, and to later fix it.
Cheers!

I've looked at the files, and unfortunately I still can't do much with them:
- the autosave is from year 1836; could you attach an autosave just before the freeze?
- the "crashes" file is empty - do I understand correctly that there were no crash folders created? If so, I'd ask you to attach zipped "logs" folder from Documents - it should be zipped after the game has froze, before you restart the game again.

I assume the crash logs are empty because the game doesn't actually ever close.

Yeah, in that case you probably wouldn't get the crash folders. But in that case we would need "logs" folder to have any chance of figuring out what's going on.

I can't reproduce the issue locally, and I don't see anything in the logs about what could be causing this.
The only thing I can do is to move this thread to Tech Support forum, maybe people there will be able to help you.
