I can't reproduce this issue. I have installed the exact same mods as were listed in the log file but everything works correctly. The only difference is that you are using the Feather launcher. Have you tried launching the game with just Better Clouds, Mod Menu, Yet Another Config Lib and Fabric Api? Can you try using another launcher?

Well, I did some more testing and it seems like the problem lies on YACL's incompatibility with feather. No matter what I did, YACL would either completely shut itself off, not even registering as a mod, or stops the client from launching. Eitherway, thank you for your research; I've switched over to modrinth (it wasn't updated to 1.21 at the time) and it works just fine.
