Try replacing the cable outer/s. Ghost shifting is most typically a cable problem. New inners do stretch & need a tweak, but the outers do wear & get grabby too. They wear where the inner runs through on bends, and get cruddy & rusty & rough.Seems like it’s skipping trying to change gears. Cable seems good (only 6 months old). My bet is on hanger.
If it's a SRAM Eagle derailleur, any level, if it's got the tiniest twist it's out of whack and totally fucked.
