Moon animator doesn't open my animation

Hello guys, I was trying to make a good cinematic animation but The last time what I did was I added the camera, after that the moon animator lagged, I couldn’t press anything and I closed the moon animator (Saved first) and Idk what’s happening now.
I can’t open the animation In moon animator anymore.
I’m pressing “Open” and It’s dragging me to the first keyframe of the camera.


there’s what happens, literally nothing.
Please help!! I’ll be glad!
