iMovie Won't Download - OS Catalina

Try dragging your present iMovie 10 app from the Applications folder to the trash, but don't empty the trash. Then sign in to the app store and open your account by clicking on your name at the bottom of the app store side bar. That will reveal your purchases. iMovie will be listed if you had purchased it before. See if you can update from there. If the update is successful you can empty the trash of your old iMovie app. If for some reason the update is not available then move your old iMovie out of the trash and replace it back in the Applications folder.

If still no luck, try booting up in Safe Mode and, after everything loads (it may take a while) immediately shut down and reboot in normal mode. Now see if you can download iMovie.

Have you changed your Apple I.D.? If you are using a different Apple I.D. than you did for your older purchases, then the older purchases won't show up and that also might be affecting your download efforts. If that is your situation you can try logging in with your old Apple I.D. If you ever had iMovie 10 on your computer it should show in your purchases even if you had deleted it, providing that you are using the same Apple I.D. that you used to purchase it.

Another way to get iMovie 10 is to sign in at the online app store, type in "iMovie 10 app" in the app store search box, and download it from there.

Glad to see that you computer is working great again.

You can go to the Finder help menu and get instructions on how to revert back to a prior operating system. Or, you can use your time machine back up to restore your previous operating system. Back up your Mac first.

To cover the bases, make sure that you have enough free space to download iMovie.

Hmmm. I have no explanation other than the problem might be related to Catalina somehow.

Might be worth trying to sign in with the older password to see what happens, bearing in mind that no purchases are shown with your new password. Nothing to loose!
