EU4 Crashing(Unhandled exception C0000005)

[Deleted user]

Prior to this, I was able to run Europa Universalis 4 without any issues, but suddenly it has begun to crash.

This is an excerpt from the crash.txt file:
Unhandled exception C0000005 (EXCEPTION_ACCESS_VIOLATION) at address 0x00007FF77DEDC951

The only modifications I've used for the game are: Graphical Map Improvements, Stellaris UI Font, Fast Universalis, Bigger UI, Cactus Cheats, and Thick Borders and Recoloured Water. I also have each and every DLC excluding the Origins DLC along with the unit packs.

If anyone is able to find a solution to this, it would be greatly appreciated! Thank you!

Sorry but we cannot help with modded games here. If you disable ALL mods in our launcher, does the game start okay?

I restarted the game with all mods disabled, and the crash still occurred. I checked the exception.txt file and it's the same. I also got this popup once it crashed.

I can only assume you have a corrupted game installation then. Please do a full **clean** re-install:

- move any valued save games elsewhere
- "uninstall" in Steam-EU4
- manually delete both the Steam/SteamApps/common/EU4 AND Documents/Paradox Interactive/EU4 folders
- re-install game in Steam, run a Steam Verify when done.
- add EU4.exe to the exceptions list of your antivirus app; ESPECIALLY if you have Windows Defender, add it to the Ransomware "Apps Allowed Through" list.
- start the game with no mods active and test with a new campaign, NOT any existing one

In particular make sure there are no files or folders left under either the Steam EU4 or Documents EU4 locations, before installing again.

Good luck!
