Crash every time i re-open c++ project

Every time i make a new c++ project, I write some code and it works fine (no errors) , so usually i build the solution in visual studio (btw is Community 2015), compile from ue4 , I click on the “Save all” in visual studio , close visual studio and close ue4. When i open again the Project it crashes , even if before closing it was warking with no error.
Is there a solution to this?
I tried to delete binaries files, generate visual studio project files but it still crashes.
I’m Using 4.14.3 version
