ue4 crash in loading

hello , when i open a ue4 project i wait some seconds the loading appears after some seconds is it closing , what i can do ?

In your project folder you should go to Saved/Logs and check what went wrong. Paste error and we can look for solution.

any project i opened it’s same result , or if i try to open ue4 to create a project

If you need to go to your auto saves and use one of them
