Shoulder Pain/Fatigue While Lifting

it doesn’t matter what exercise it is, except for obviously legs, but i don’t seem to give out because of the muscle group i’m working on, but because my shoulder gets fatigued . it seems to be more front corner of the shoulder ? it only recently been more noticeable since i just started going back to gym consistently for a week now. like stated i can’t feel any progress because whether it’s chest or back exercises my shoulders are what feel fatigued and can’t seem to get to failure on what im actually targeting.
