Game crashes, typically on initial of boss fights. 0xc0000005 0x00000001412E9214

Getting rather consistent game crashes, typically on the first attempt of boss fights.

After restarting the game, the boss fights goes on without issues until the next map/instance boss.

Getting the same error both in Windows 11 and Linux, so it doesn't look like a typical OS / driver issue. Game is installed separately, but it is the same computer. I've not been able to reproduce the issue on other characters, only my PF Poisonburst Arrow build seems to be affected.

I'm adding some information from the Linux Steam proton logs as they are far more inclusive than typical windows logs.
There is more stack trace available, let me know if I should add it.
