Shadow Monsters (D5F2428) crashes for Nightrunner of Mask

Hello, new to the forum and mods, old school BG player. Trying to make characters to match my favorite fantasy series. Aiming for a Nightrunner of Mask dual class to Mage.

I have changed up the mods dozens of times and I can't tell if it is caused by the kit, the spell, the casting graphics or something else.

Possibly related issue: Can't pregenerate characters and export them, but I can start them up in a party and save and load fine.
