Crash Report file and latest.log

https://mclo.gs/eIvbM1H <- just iris and performance mods to test that iris was the issue
https://mclo.gs/Cd6ahEA <- my modpack with a fuckton of mods and such (with iris)

Additional context

i have a heavily modded version (log for that one here) and one that just has a few performance mods and iris. i wanted to make sure it was iris that was making it crash. anyway i have no clue why this is happening um. sorry for confusion im exhausted and have very little time to fuck with this

Hi not a dev of Sodium or Iris here, but the Sodium 0.8.12 backport alphas are incompatible with Iris rn so you need to swap it with Sodium 0.6.13, obtainable at https://modrinth.com/mod/sodium/versions?g=1.21.1

For anyone who sees this and still has issues after downgrading Sodium:
If you have More Culling installed and updated to 1.0.8 you have to downgrade it to 1.0.7: FxMorin/MoreCulling#444
