One of the strangest glitches I've ever seen.

I keep having this issue (1.19.2 FORGE Version) where I pick a race that spawns in the nether (Blazeborn/WitherWraith(MedivalMC Modpack)) and upon dying and pressing respawn, the game softlocks itself by trapping(?) your character inside of itself, unable to move, able to hit and kill yourself, cannot move in any /gamemode whatsoever, and even Respawn Anchors don't detect if you died.
I was even able to kill myself in creative mode... with my fists...

Weird glitch that happens every single time I try to choose a class that is coded to spawn you in the nether. Modpack glitch?

Most likely a mod interaction, can't reproduce in my test environment.
