It keeps saying "Incompatible Mod Set!" when I try to load in my MC. What do I do?

Description

I downloaded some mods to start a new modded world. But after fixing the first issues, it just kept saying "Incompatible Mod Set!"
It was because of the fabric loader file. So I tried downloading Fabric in different ways, even looking up videos online to see if I did it correctly.

If you're using Minecraft Launcher you can update Fabric Loader by just running the Fabric Installer again

Thanks! I redownloaded Fabric Loader to make sure it was a clean install. I also updated my old fabric loader, it worked incredibly well. Thanks so much.
