Debug not working #2602
Description
when trying to debug on a fresh (Windows) install of Arduino IDE 2.3.4 and Srduino_Core_STM32 2.9.0 on Nucleo L4R5ZI I get the following error message on a first debug attempt

I then realized I hadn't set the debug options and also reset the board
on every subsequent debug attempt, I then get:
