Error g0x9-spelpwp1p2nt, game constantly crashes on alt

I just made my first alt and powerpassed it. After doing a few chaos dungeons, I interacted with the Adventurer Helper quest in Vern and got this error at the end of the interaction.

Tried updating drivers, running as admin, verifying game files and none work. I can still play on my main without any issues, only the alt has constant crashing and is unplayable.
