Ask around - there must be someone who upgraded their left arm to a power arm and has a spare now. Or just buy a left side arm (assuming the right hand side is still good).

Also check the bolts several times when installing the new crank arm. It's fairly common to hear that people only torque each bolt once. Torque both alternatively several times.

Is it possible to buy only 1 side ? I've been searching online all morning

Crank hit a rock in the beginning of a 50k ride yesterday.Not sure if that's what maybe did it in
