My entire scene is missing, and when i create a new level it is still missing

I was following a tutorial about playing a video on a plane and after enabling a plugin called electra player, and restarting my entire scene is just gone.

I tried deleting my sky and everything is still hidden or missing.

I have figured out the solution, it is because I adjusted the near clip plane to a negative number. but it only takes effect after you restart.
