The soldering work looks pretty rough (practice on a throwaway project first). Probably one of the TRRS or MCU pins is not well connected. Get out a multimeter and do a continuity check of all the connections. It could also be misconfiguration of QMK, but make sure the basics (hardware connections) are right first.
