Debug "PICO" RP2040 some who have success with it

Are there any that are successful with Debugging RP2040 “PICO”
I can fine upload and run it blink.cpp and others

Debug starts and breaks at setup
Call Stack “dump”

If I put BreakPoint in the loop it stops Sometimes once) I almost never, if i make a manual break after a while
