Tends to powering issues

Check part orientation

Check SWD pins​

Check NRST level​

these are my schematics

  1. WIn11 maybe not good choice
  2. Debug in ?? IAR KEIL IDE
  3. Bootloader debug is ... impossible
  4. Enable debuging in low power modes ...
  5. Is you firmware loaded and how stack is in coprocessor? Use SWD under reset mode

And swap
