When trying to load the game with mod included it quickly crashes. Problem does not occour when mod is removed.

Using Fabric version 0.16.7

Yup, it crashes no matter what I do in this version of the game (1.20.1). Using version 2.0.1 on Fabric 0.16.5 and 0.16.8... even if I don't have any other mods installed besides basic optimization mods.

Here's my log too if it helps:
latest.log

I also have the same issue in 1.20.1, I tried it with v2.0.1 and v2.0.0, crashes on both with different error messages but both are about the java version.
This was the error from v2.0.1,
[00:06:44] [main/ERROR]: Minecraft has crashed!
net.fabricmc.loader.impl.FormattedException: java.lang.UnsupportedClassVersionError: net/minecraft/class_3218 has been compiled by a more recent version of the Java Runtime (class file version 65.0), this version of the Java Runtime only recognizes class file versions up to 61.0

I get weird crashing as well, although maybe it is because I am using 1.20.4.

Still doesn't work. Also, strangely, it auto-downloads 1.20 fabric api as a dependency for some reason, even though the mod is for 1.20.1, which causes a crash, if you upgrade the api it crashes for a different reason. I know older versions are usually not supported by mod devs, but basic maintenance for stuff that entirely prevents the mod from being usable would still be appreciated, especially since 1.20.1 is still the most used version by many players for modding.
