Most likely it's Sodium's fault.

You are using build 359, use this build instead. https://github.com/FlashyReese/sodium-extra-fabric/releases/tag/mc.1.16.5-0.3.0-next-compat

The build I linked, and by build 359, I meant Sodium next build 359.

I keep getting crashes when trying to open graphics settings with Sodium Extra 0.3.0 and Sodium dev build361.

Removing SodiumOptions from sodium_extra.jar solves the problem.

You aren't using the build I linked, https://github.com/FlashyReese/sodium-extra-fabric/releases/tag/mc.1.16.5-0.3.0-next-compat

The crash log you uploaded says that you are using the normal release.

Excuse me, what build?
