So I tried modding the game with BG3 mod manager and it made my game unplayable. I have removed all the mod related files or so I thought. However the mods folder and the mods.xlx file keeps repopulating when I play. I went into local app%data and got rid of the files, the modified steam files and yet Gale's portrait remains the white wizard modded look, and it crashes anywhere within a couple hours to ten minutes of playtime.
Where are you launching the game from?
Is the game actually installing the mods or is it just the folders repopulating?
The Gale thing could be because the info is still in the ave. Have you tried stating a new game?
A bit more info on what you did in the first place may have helped.
