try to open your project from the Source folder. You will find a folder with the name of your project and inside that folder you will find all your c ++ files. with opening any of them the visual studio will open and press the “local windows debugger” button. If compiling generates the same error, try to modify your code commenting on the last changes you made. and go back compile again. I have sometimes resulted in that way. I hope it resolves!

I have never run C++ stuff in ue4. So i can t find this files that you mention in my folder’s project. What can i do?
