Does your code reconfigure SWD pins on GPIOA? Do you enter low power modes?

You can't debug if the SWD pins are reassigned elsewhere.
Debugging in low-power mode is possible but generally not enabled by default. Look in the appropriate reference manual for how to enable it, generally within DBGMCU.
