UE4: Unable to start debugger in Visual Studio

I have my unreal project opened in Visual Studio. When I press F5 to start the debugger, it shows the following error message. "Unable to start program 'C:\Program Files\Epic Games\UE_4.22\Engine\Intermediate\Build\Unused\UE4.exe'."

It is because UE4 was set as the startup project. To fix it, go to the Solution Explorer in Visual Studio, then right-click on your game project > Set as StartUp Project.
