just downloaded new version and now I can't open itI am using MAC Big Sur 11.6.2. - any advice welcome.The app had downloaded - a message said I had to close the app (which I did) now it won't open.THANKS for any help
It isn't possible to revert. I guarantee the issue is not the new version.
You can try temporarily moving the cache folder to the desktop, and reopening the app. If it works, you can try moving files / folders back one at a time to isolate which imported file caused the issue.
The cache folder is located here on MacOS:
To easily get to this folder, use the GO menu at the top of the Finder, and select GO TO FOLDER, and copy that address into it.
Please try deleting the app from your Applications folder then restart and reinstall from the App Store.
