Just an update, I have the error here and no illegal characters in my pathway. Here it is for record:
"C:\Users\Wes\Documents\Larian Studios\Divinity Original Sin 2\Mods" please let me know if there is something else I can do to get this working and thanks for your hard work.

Check that your game is up to date, and that you aren't using any out-of-date mods, such as one that was "converted" from Classic, since if it has story scripts, they will be incompatible out of the box.

I do have a question, if you move your mods over to the other user's Documents folder (I assume that's what you mean), will it still know where to find them? Or did you mean playing the game in the new user?

Trying to use the other user save and load it on your regular one will give you a message and clear your journal, essentially stopping you from progressing anyway...

I meant playing the game as the new user, yeah.

running into issues with mod, tried making anew profile and it did not work, stumped on what to do

Mine is the same, hoping an answer will come.

I've had reports of this error across a few of my mods, and it seems this is caused by having non-ascii/latin characters in your folder pathway to your mods folder.

Until an official fix happens, you can work around this by creating a new user account with latin/ascii symbols. Then from there, you can move your mods over and play like usual, or you can use that new account to make a save and transfer that over to your old account.

Just know that if you go the latter route, adding new mods to the save will result in the story errors once more, so I recommend just using a new account until the problem is fixed.

Could you give an example, please?
Do you mean a new user account on my computer or on the game?

I didn't change any user, which ever it might be, but I turned off all my mods and started new games (just went as far as character creation, so no problem on that). So I turned on my mods one by one until I found a incompatibility. In my case it was a Taunt mod so I just turned it off and the Party Size mod now works perfectly

The user account thing was for people who had non-ascii characters in their Windows username. DOS2 had (or still has?) an issue reading mods from their documents directory.

If the mod you're referring to is "Taunt Makes Sense", it says it requires the script extender, so that's not a compatibility issue, but an issue of missing a dependency (Norbyte's script extender).

Working story errors usually mean you're missing a mod dependency, or the script extender, if a mod requires that. When you have a mod using some scripting stuff that doesn't exist without the dependency being active, the game has an error when it goes to compile story scripts.
