Ue4 stopped working?

Whenever i start up my pproject it gives an error that it stopped working but when I create a new and then open the new one it opens…WHat is the problem?

Would like to suggest just a way around.You can copy your content folder to a new project and then open up the new project so that you can continue to work on it.This might not resolve your issue but it will help you to recover some of your files if you are in hurry!!.

Try renaming the “saved” folder of you affected project usually you can find it in the “C/user/“pcname”/documents/unreal projects/“projectname”” in explorer to something else and then start the project.Sometimes this might also resolve the issue.
