I am using a Nucleo-F103RB dev board with Cube IDE 1.3.0. I am able to successfully flash the board (which I have tested by making the user LED on the nucleo toggle at different frequencies), but immediately after this is successful, I lose connection to the debugger. I have the SWD pins enabled and the debug mode set to SWD and so on. Here is what the console prints out:

The debugger loses connection immediately after the download is completed. Everything after "Debugger connected" prints at the same time.
If I go to debug mode, it says there is a suspension at HAL_Init(), which cannot be the case because I have confirmed the program is successfully running on the board. I have checked other posts with the same problem and they are not relevant to my question as I have always seen that their solution was already the case for me. I have also attached a screenshot of the debugger tab in Cube, but haven't changed anything from the default settings.
