what is happening

This is happening because an update to Quilt Mappings breaks QMoL. The reason this isnt super important is because the QM update deprecates QMoL.

use the following code for mappings instead of loom.layered { ... }
mappings "org.quiltmc:quilt-mappings:${project.quilt_mappings_version}:intermediary-v2"
