V5 controller prevents motors from spinning when connected to brain

Hi,

I have a controller that, when connected to a brain, prevents the motors from spinning either through code or using the devices menu on the brain.

I have tested this controller with multiple brains and radios and the behavior is always the same.

The motors will spin when:
Other controllers are connected to the brain.
No controller is connected to the brain.

The motors will not spin:
When the weird controller is connected via radio.
When the weird controller is connected via wire.
