I'd concur with Muskrat and from the picture it appears your sprocket on the clutch basket also look fairly worn, which if poorly aligned could be hooking up when you pull in the clutch.
Tie the clutch lever to the bars so the clutch is disengaged and look at how it rotates/aligns, chain alignment is important.
But your front sprocket tooth profiles look far more healthy than the clutch sprocket teeth do.
