Reproduction Steps

Basically, whenever I try to join a single-player or multiplayer world (on 1.16.1) I get the loading screen and I believe when it spawns me in so when it's about to show the 3D graphics the game crashes with the crash log below.

Ah, you have compiled it with a Java version of at least 9. This is known to cause problems when run on java 8.

You could use the precomputed version, make your Minecraft use a later java version or compile with java 8.

That seems to have fixed it, thanks for helping :-)
I seem to have missed the warning notice in the readme.md
