the easiest best long term solution is remove wall completely and
regrade yard, plant groundcover on slope.

no wall means this will never happen again.

retaining walls fail way too often. and few want to spend the bucks on
a real solution.

with a proper footer, below frost line and all the rest to do a good
long term job
