I'm posting this here to be referenced by devs/helpers in regards to sodium extra information's 1.21.1 beta being completely broken.
from the crash report it seems to be sodium extra, but it is simply because the sodium extra information developer posted a broken beta to curseforge and does not say it is broken.

Honestly, I don't see why that mod is needed. If you really need more than FPS and coordinates you should be using MiniHud
