Metahuman missing Binding asset for some Groom asset

Was having a similar issue and solved it after following the solution from this thread:

UE 4.26 Metahuman Hair, Eyelashes not moving with Metahuman Rig

[Metahuman_hair_not_working] The hair of my metahuman stays fixed in place, when i use it with the metahuman rig. I dont have this provblem when I just move the metahuman around as a whole, only with the rig and it was working before for a long time and just happened all of a sudden. Tried it with UE4.26 and UE5 and uninstalled everything but the problem remains the same.
