normally I can decipher the fabric error messages but I don't quite understand this one, every time i try to launch this mod I get this message. I have tested the mod multiple times on its own with the vanilla launcher and otherwise and keep getting this code, even though this is the newest version

Incompatible mods found!
net.fabricmc.loader.impl.FormattedException: Some of your mods are incompatible with the game or each other!
A potential solution has been determined, this may resolve your problem:
- Replace mod 'Sit's End Anchor' (endanchor) ${version} with any version that is compatible with:
- fabricloader 0.15.3
- minecraft 1.20.4
More details:
- Mod 'Sit's End Anchor' (endanchor) ${version} requires version ${loader_version} of mod 'Fabric Loader' (fabricloader), but only the wrong version is present: 0.15.3!
- Mod 'Sit's End Anchor' (endanchor) ${version} requires version ${minecraft_version} of 'Minecraft' (minecraft), but only the wrong version is present: 1.20.4!
