Resourcepack broken in 1.20.5 snapshots

Equipping the attached resourcepack in 1.20.5 snapshots fails while working fine in 1.20.4
It fails giving this error Shader rendertype_entity_translucent_emissive could not find sampler named Sampler2 in the specified shader program.
I tried deleting all shaders (since i basically don't know how half of them work) but that didn't seem to fix it, leaving me with no idea what the issue could be
