What could be wrong if my rear left signal doesn't work after changing bulb?

I would doulbe check the bulb first. If the bulb is in good working condition use a multi meter to measure 12 volt at the wire harness where it connects to tail light.

The wires inside the tail light could be damaged.

If there is no power going to the rear left signal at all, there is a good chance this is bad SAM module. It will need further troulbshooting to confirm. Also pay attention to other electronics functions. Usually when the SAM fails, you will have various systems starting to act up.
