Larian Studios Forums Baldur's Gate III Baldur's Gate III - Modding Toolkit error, please help...

I've been trying to follow the guides to create a new class and subclass through the toolkit, but when I attempt to publish, I can't open the Project Settings. Instead, I get an unhandled Exception error saying "an item with the same key has already been added".

Does anyone know how to fix this?

Following is my DXDiag report (note: Windows Error Reporting and other telemetry are deliberately disabled on my system)...

Let me know if you have any trouble accessing it there.

Thanks,
Azrael

I know this is old but I found this from google, in case anyone else ends up here, I renamed my Mods folder in here

C:\Users\%username%\AppData\Local\Larian Studios\Baldur's Gate 3\Mods

and that fixed it.

some one of my mods was having duplicate IDs, the toolkit seems to load all the mods there instead of what is chosen so it's pickier then the actual game.
