@mlengka93 i found a temp fix until mod dev can fix it themselves open couplings jar file with winrar etc and edit fabric.mod.json and change "depends":{"fabricloader":">=0.4.1 <0.5.0"}, to this "depends":{"fabricloader":">=0.6.0 <0.7.0"},

just remove the upper bound entirely. it shouldn't be there, no idea why it's there in the first place
