Minecraft: 1.16_combat-6
Mod: 2.0.1+1.16

Details

The game crashes when I use the latest 2.0 release but does not crash when I use a 1.0 release

Please run the game with -Dextrasounds.debug=true added to your Java arguments and attach a log file as well.

@stashymane why was this closed? it isn't resolved yet

May have closed this when mass-closing the 1.19 issues, my bad

Hi I believe the source of this issue is the following error which occurs in the 2 most recent 1.16.5 releases of the mod:

net.fabricmc.loader.impl.FormattedException: java.lang.UnsupportedClassVersionError: net/minecraft/class_1657 has been compiled by a more recent version of the Java Runtime (class file version 60.0), this version of the Java Runtime only recognizes class file versions up to 52.0

I'm not exactly familiar with fabric but looks like your target java version is too recent? 1.16.5 uses java 8 I believe

Yes, I may have compiled with Java 16, but there are a few other issues blocking an update, the main one being a severe lack of time. I'll try my best to work on the mod in a week or two.
