Internal short on axis 0?

I am using an ODrive 3.6. I can run the full calibration sequence on Axis 0 with no issues. With the same setup but swapped axes I get an EncoderError.NO_RESPONSE. I will note that the motor does rotate during calibration for axis 1.

It appears that only axis 1’s encoder connection is an issue. I found out that there is a short between ground and the B channel pin. But I cannot find any kind of obvious short between them. I unsoldered my custom headers but that made no difference. If this is an internal short, is there any way to fix it?
