“GDB server stopped unexpectedly with exit code 1”

In settings:

Everything is updated to the most recent versions, I tried all the options from the internet, nothing helps.

In Visual Studio Code with PlatformIO debug work, but every start in rebuild all files in project. It’s to looooong. (About 1h).

There are only 18 devices in official support, but this does not bother everyone else. The problem is clearly not in the board, but in Mbed Studio. In PlatformIO, the debug works fully, with the same MbedOS. However, there is another problem, why does it constantly recompile all the code, but I can’t wait for each launch for 1.5 hours.
