If the projects you are working on were created in iMovie, click the "Projects" button to find them.

See how to: Work with projects in iMovie on Mac - Apple Support

For any older projects:

If necessary you can: Update projects from earlier versions of iMovie - Apple Support

Re: " ... is theatre on longer available in imovie?"

See the latest info.: If you’re looking for iMovie Theater in iMovie on Mac - Apple Support

Eg: says:

"Sharing to iMovie Theater is no longer supported. If you’ve shared movies or trailers to the Theater in previous iMovie versions, you can still view, share, and delete them. To continue to view movies or trailers you’ve shared to the Theater on all your devices, import the movies or trailers into Photos and make sure iCloud Photos is turned on. After you’ve imported all your movies and trailers into Photos, you should delete them from iMovie Theater."

Hi,

Every time you close a project that you are working on it automatically saves to the Projects Browser library. You can access it by clicking on the Projects button at the top of your iMovie screen. Your project will be displayed as an icon in the Projects Browser.

You can export (share) a project to your desktop (Finder) as many times as you want. The editable project itself will remain in iMovie in the Projects Browser library. In your case it appears that you have exported out the project to your desktop or an external drive. As mentioned above, you can access the editable project in the iMovie Projects Browser.
