Question
CubeIDE debugger fails to load the binary - SOLVED

To end the horrible winter night... even the debugger fails in CubeIDE under Windows.
On the same Windows machine CubeIDE can debug the same target in a Linux VM.
Isn't it curious?
Same error with OpenOCD and ST-LINK GDB server.
Of course, Atollic just works.
Could this be related to failure to convert ELF to any other format?
