I am trying to flash the STM32F723E-DISCO debugging board, here is the log:

There seems to be an issue with connecting to the debugger.
I also cannot connect to the board through STM32CubeProgrammer.
However, if I flash the board with a project from STM32CubeIDE, everything works and the programmer connects as well.
It appears that something is breaking in platformio.
