My project does not give preview

When I try to open my project it opens, I can edit the events and etc, but when it comes to previewing to test the game I can’t, the project tries to preview but stays on the same screen for a long time.It doesn’t leave the editor, it doesn’t go to that black loading screen, it just tries to preview and then stops.

It’s a problem with this project, because the other projects I have open and preview normally.
