It's a USB, use it, plug a USB keyboard in to the USB socket, ie the one on the Pico, then type:-
OPTION SERIAL CONSOLE DISABLE

But why?

then blind type
OPTION SERIAL CONSOLE GP20,GP21,BOTH
or whatever gp numbers you are using?

Obviously wrong answer, correct is that he can use an attached USB keyboard to change:

Loaded HDMI USB firmware and typed:-

option serial console gp21, gp20

And it changed the console to gp21, gp20 instantly with no errors. So that is all you need to do, ie don't include COM2,.
