I'm trying to update Fabric mods for 1.21.6 and I keep getting an Incompatible Mods error. The only mods I have in the folder right now are Fabric API, Cloth Config, and Architectury and those need to be functioning first before any other of my preferred mods will work. I'm really confused what is wrong.

06/21 - further information: no matter how many times I try to download cloth config from Curse Forge, I get 0 data in the file. Of either version released for 1.21.6.

OK I solved my own problem. xD Download from Modrinth, not Curse Forge. Sorry to waste anybody's time, but if anybody else is struggling, don't use Curse Forge.
