Got a lot to say but if any detail helps, I'm putting it out there. My game is modded and was working fine until patch 7 came along. I updated my mods to accommodate the new patch. The mod manager now says that the game data folder is not valid. Right now I have it at games\baldurs gate 3\data at the recommendation of asking another forum. Previously, it was C:\Program Files (x86)\GOG Galaxy\Games\Baldurs Gate 3. If I tried to play the game would slow down to a quick halt after the cutscene that introduces Minsc as that's where I am. I just disabled ImprovedUI and that somehow let's it run (albeit at a really choppy pace). Does anyone have any idea on how to get it working?

you should restart a new game after loading each patch i.e, patch 5 to patch 6 = start again and patch 6 to patch 7 also = start again

that said, how many actual mods have you installed?

I can give you the list if that helps. Right now, I'm considering replacing some of these mods with their first party equivalent and seeing if that helps.

ImprovedUI, 5eSpells and the List, UnlockLevelCurve and the spells that go with that, Artificer, CompatibilityFramework, Community Library, Fantastical Compendium and a good number of the races that it came with, Pirate subclass for rogue, roguesextra
