With sensor cable plugged in you can't just reverse any two wires like you would/could in unsensored anyway, it has to be A-A, B-B, C-C.

That aside I don't really know what could be causing it since the senor cable and the sensor board itself seem to be working otherwise. Sometimes there are rare cases where a motor and ESC can be incompatible in sensored mode, maybe you stumbled into such an occurence.
