M10-P stuck/sticky rangefinder - lens issue and/or camera?

took out my M10-P that hasn’t been used in a couple years to take some photos and then after a while the range finder stopped tracking when rotating the lens focus ring.

i’m reading that it could need lube on the rangefinder coupling arm. do you think the issue is caused by lack of lube due to long storage time or is the lens out of alignment and causing the issue by asserting too much force on the coupling arm?

i’m trying to determine whether should i repair just the camera or both camera and lens.
