Cannot update or use iMovie after updating macOS

I own a 27 inch iMac (late 2013) and yesterday I upgraded my operating system for the first time, from Yosemite, to Mohave, to Catalina (as new as my computer can allow), and now iMovie will not work, so when I go to the app store to update iMovie, it says I need macOS 11.5.1 or later, but the problem is that the version I have is 10.15.7, and thats as new as I can go. (See Screen Cap). Now I cannot use iMovie, and I cannot download the new version, and I really could use some help. I make and edit videos for my business constantly and need access to this software badly. Please help.

Try this procedure to get the highest iMovie version that your operating system will run:


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.
