Sponge is a Vanilla or Forge mod… it does NOT officially work on Fabric.

That said, as of now Sponge doesn’t even have a build for Minecraft 1.16.2

-edit: after looking at that, it looks like it’s the Sponge Mixin system that is failing, which probably works on 1.16, however I do not think the crash relates to sponge at all - there is likely a mod conflict or issue instead.

I would try going through your mods (half at a time or something) and try to find the one causing the crash, and reporting it to that mod author
