Game (v.1.31.0.0) crash in certain date?

[Icing World]

I was playing Rev. Spain the whole time
Just pass the revolution by 3 years.
over 100 messages pop out for loss of war cause, I don't know does it affect the crash.
The game crash in 1752.01.21
I tried to move the date pass 21st but that does work
I am hoping for getting a useful solution
The game is played with one mod which is Graphical Improvement.
Not in Ironman.
Thank!

Version 1.31.0 had many crashing bugs. Does it help if you update to version 1.31.4? That version should be compatible with 1.31.0 saves. If that doesn't help, you can also try 1.31.5 or 1.31.6, but that causes some broken monuments on old saves. For a new campaign I would recommend that you update to 1.32.2 or 1.31.5.
