Might not be the problem but when you plugged the batteries in one of the power pins seems to have popped out.
A circuit diagram of how it's wired to your Pico will probably help.
My guess would be the amp is drawing more current than the batteries can supply causing something to collapse in the process. What rating are your batteries ? If you have a current limited power supply you can connect that and see what happens as you reduce the current.
