Strange, maybe the cause of the problem is electromagnetic interference generated by an external source.

I think the card is tested "as is".
The length of the wires should not be a problem but the electromagnetic disturbance generated by an external source that affects an circuit by electromagnetic induction, electrostatic coupling, or conduction.
Please use shielded cables and connect the shield to the GND terminal of the board.
In very "noisy" environment, put the card in a metal housing and connect the housing to the GND too.

Yes, connect the other end of the cable shield to the ground of the external device.
