Error "Unable to start a new game. This may be due to installed mods containing invalid Osiris scripts, or the use of Mod Fixer (harmful since Patch 7). Please disable or update mods and try again!"

Hi, I have a problem and I don't know what else I can do. Every time I try to start a new game in BG3 with mods, I get this error: "Unable to start a new game. This may be due to installed mods containing invalid Osiris scripts, or the use of Mod Fixer (harmful since Patch 7). Please disable or update mods and try again!" I don’t know what else to try. I’m trying to use a mod collection called "Nolvus", I’ve tried other collections, I’ve installed mods manually, and I always get the same error. I’ve tried uninstalling all the mods and reinstalling them several times, I’ve also tried uninstalling the game and launching it vanilla before installing any mods, and nothing. I don’t know if this is only happening to me — if anyone has any idea or knows how to fix it, I’d really appreciate it.
