[SOLVED] - CubeIDE not downloading and restoring previously downloaded code

[SOLVED - It was a bouncy ground on the programming connector on the second PCB]

Hi,

I have two version of the same PCB only with minor HW differences which also require minor SW differences. So I made a copy of a project folder that works and renamed the folder. Then in CubeMX I also renamed the project itself.

It compiles but when I try to download it onto the micro - using the same Segger's J-Link I always use - it:

1) does not download the code onto the micro

2) instead of opening the source code window it shows error:

No source available for "(gdb[6].proc[42000].threadGroup[i1],gdb[6].proc[42000].OSthread[1]).thread[1].frame[0]"

but the main() source file (and other ones) are there and already opened.

3) it restarts the PCB running the old code (extremely different in functionality including which LEDs are on, so it's very obvious it is the old code)

The output window is shown below. From the output window, it seems the communication between the J-Link and the PCB is ok, which also seems to be confirmed by the fact that CubeMXProgrammer does read the chip memory.

But even in that output window it shows some errors. What might be the cause?

This is the full output:
