Bl2 tiny Tina dlc crashes on entry of immortal woods pc

I am on pc and am playing a boosted zero playthrough. I am at the part in the tiny tina dlc where you must enter the immortal forest after opening the big stone door. When I try to go through the portal to the next map the loading screen appears as usual but then shortly after a message pops up that says, “invalid number of texture coordinates” along with a bunch of other information below. everything else in the game works fine it is jus this one spot. does anyone know anything??
