Edit: On further testing, this appears to be due to Oculus incompatibility.

Loader: Forge
Version: 1.20.1
Mod Version: 1.2.3

wow that's terrible.

I've been having this same issue, I've had the mod installed for a week or two now but this didnt start happening until today. I haven't changed or updated any mods. I also haven't changed any settings either.

I don't know what could cause this

After uninstalling oculus the issue is resolved, so its likely just an incompatibility.

Nothing to add but wanted to confirm the issue. Removing Oculus fixed it for us.
