The selection cannot be launched and there are no recent launches stm32cubeide

Hello all,

As a C++ Programmer who aims at starting learning embedded programming on Arm based MCUs using C++, I went for this tutorial to program my STM32F411RE Nucleo-64 board for the first time. At stage 5 in that tut, when I need to debug the project, I get the following error message:


I tried to find the issue and work it out but no success yet! 
Do you have an idea what the problem might be and how to solve it, please?
