Hello, I updated to Catalina at the weekend. Ever since I cannot open App Store. the message The application “%@” can’t be opened. appears every time I try. The problem report tell me App Store quit unexpectedly while using the AppStoreKit plug-in.
Anyone have any ideas please?

Hi PerplexedwithCatalina,
Thanks for reaching out in Apple Support Communities. I understand that you're unable to open the App Store on your Mac after upgrading to macOS Catalina. I see you're getting an error that the App Store can't be opened and the report indicates it's quitting unexpectedly. I know how important it is to be able to use the App Store on your Mac; I'd like to help. First, start your Mac in safe mode and try to open the App Store: How to use safe mode on your Mac
If the App Store opens successfully in safe mode, restart your Mac normally and test again. If the issue persists, I'd suggest reinstalling macOS Catalina: Reinstall macOS
Let me know what you find.
Best Regards.

Hi PerplexedwithCatalina,
Thanks for taking the time to try safe mode and get back to us with the results. I know it's important to have a backup before proceeding with a macOS reinstall, so let's look into that. I suggest using these steps to troubleshoot the behavior you're experiencing when attempting to back up: If you can't back up or restore your Mac using Time Machine
Once you've created a recent backup of your Mac, use the steps previously provided to reinstall macOS and thereby the App Store.
Take Care.
Thank you but safe mode makes no difference.
Has anyone encountered this problem before?
So rry, somehow I clicked solved but this issue is no way solved. I also cannot back up to my NAS.
