Never had any issues with iMovie previously, but now when I attempt to save/share to "file" the application simply quits. iMove version is 10.1
If it helps, I recently upgraded to Sierra 10.12.6. Never had this problem when running on El Capitan.

Be sure that your iMovie version is updated to the highest that High Sierra will run. You can use this procedure:
To update/redownload iMovie 10, drag your iMovie 10 app from the Applications folder into the trash, but do not empty the
trash. Sign in to the app store and open your purchases folder by clicking on your name at the bottom of the app store side bar. You will see your purchases displayed, including iMovie 10. Redownload/update iMovie from there. If not successful, drag your present iMovie app out of the trash and return it to the Applications folder.
If no luck, try these diagnostic procedures:
Deleting Preferences
Open iMovie while holding down the Option and Command keys and select to delete preferences in the box that appears.
iMovie will open in a new library. Reopen your old library to get back to your projects. Deleting preferences is a safe procedure that will not cause data loss or disruption to your project.
Safe Mode
You could also try booting up in Safe Mode (see Finder menu for instructions) and, after everything loads, immediately shut down and reboot in normal mode. Then see if iMovie works properly.
Resetting the System Management Controller
Try resetting the System Management Controller (but no longer available for the new M1 computers):

I plan to try this as soon as I can figure out how to log in to the App store. It's not available in my system preferences and no longer works with my version of Safari. Google Chrome would not open it either. I'll try through iTunes.
Got it. Thanks, this seemed to do the trick.
You are welcome. 😊
