iMovie for Catalina
After an update to Catalina, iMovie doesn't function anymore. I dragged it to the bin and tried to update through my purchases - as recommended here, but it doesn't appear under purchases in the App Store. I tried to update an old version through the internet archive, but my computer doesn't want to open that because it isn't safe.
What can I do to install iMovie again? Please help, I have a lot of work that would get lost.
Thanks, An
