Failed to execute MI command: -exec-run

Question

Have win10 and just installed Eclipse Cpp 2019-06 and CygWin as toolchain. Created a first C++ progject via "C++ Manage Build" and the example "Hello World C++ Project" with toolchain Cygwin GCC.

It worked to build and run it as Local C/C++ Application and the text gets printed.

But when trying to debug as Local C/C++ Application I get this error:

Failed to execute MI command:
-exec-run
Error message from debugger back end:
During startup program exited with code 0xc0000135.
