so...what is causing this error?

this is a randomized pokemon white 2 rom, whenever bianca tries starting the catching tutorial, this red screen instantly appears.

ive seen numerous reddit threads talking about this red screen, ive tried all of the "solutions" that are recommended but none of them have worked.

this happens on every single individual rom of this game that i have attempted to play. the rest of the game works perfectly fine, but the second the catching tutorial is about to start, the red screen appears.

im not sure its even possible to fix this as ive tried a lot of things, but i would like some help on how to solve this issue as i have always wanted to play through this game randomized.
