A specific uproject doesn't open. just doesn't respond.

Hello!
I’m trying to open my uproject but it doesn’t respond and not opening.
NO unreal start pop up window.
unreal engine pops up briefly in the task manager, pauses, and then just disappears.
Nothing happens after that, and then It seems, no associated Unreal programs running on task manager.

Other uprojects are opened well but this one.

I use 5.0.3 ver.
and I’m trying to remove engine and re download, but still not working.

I must have to work with this file or contens.

Is there any way to open this?
Or Can I move this contens file to a new projects without opening this?

Plz help!
