Crack between bricks in retaining wall

25 foot long retaining wall, 3 feet high. There is a gap between two bricks which is one inch wide and 7 inches deep. Layer of bricks sits on concrete blocks. All other joints look good. Maybe this was caused by settling or movement. Should I just fill in with mortar mix? Pic is looking down at gap. Sidewalk on left (3 feet below) and soil is on right.

Something moved. If you cannot figure out why, then that problem is likely not ongoing. Yes, I would pack the joint with mortar.

A 3' tall wall constructed of brick/block is going to be susceptible to movement which is dependent on how it was constructed, back filled, and drainage, At this point there really isnt much you can do but patch it up and hope it holds together.

It is hard to say only seeing the area from above. Yea, you can fill the gap with mortar but I expect it will crack again as the joint continues to move. You can see the thickness of the old mortar in that joint and the gap has widened to 3x that. There is no quick and easy fix.
