Hello!
I moved your post here from another thread, looks like you posted it in the wrong place. 
Since this is a game issue, there’s little we can do. We do not have the tools to look further into this, whereas Ubisoft does.
The only thing we can suggest is to verify the game files, in case something in the game files has become corrupted. Which would be the fault of the Windows operating system, not yourself, WeMod nor Ubisoft. Corruption happens randomly and for no apparent reason at all. Verifying the game files will fix any corruption for you, if that’s the case here. Here’s how to do it: https://www.ubisoft.com/en-us/help/connectivity-and-performance/article/verifying-game-files-in-ubisoft-connect-pc/000060529.
