scene recovery after upgrade,How to recover project scene after a Unity3D upgrade?

I’m new to this, I’m busy with a simple game in unity and I decided to upgrade unity. I’ve seem to have lost everything in the scene, but all my scripts, sprites, prefabs, sounds, scenes folder in my project are all there. What do i need to do to have my scene back. Thank you

Did you try checking to see if the scene inside the scene folder opens up with all your stuff correctly?

HI, thank you - it did work.
