General • Re: problem with a very simple circuit

It may be your earth configuration and size of ground wires creating an offset between the Pico's ground and the transistor’s ground (unlikely but possible).

Or it could be the transistor breaking down, what transistor is it?

Are you sure you are switching the GPIO between output states and not leaving it floating?
