@Vero Thank you for the v4.0.5 update. Everything is now working as expected under Catalina.

No they didn't. The "macOS Applications folder" checkbox is ticked. Going through the macOS index rebuild from Alfred's Advanced preferences, there are no error messages in Terminal. I saw in another post, about problems finding apps with Alfred, the Alfred metadata tool, so I ran it to check. Attached is the output for the Typora app. The one thing that I did do prior to installing Alfred v4, was to uninstall v3 using a third-party uninstall app. I don’t see why this should have any relevance, but I thought I would mention it. Spotlight finds the apps without a problem and Alfred finds the apps that come with MacOS, such as Notes, Mail, Calendar, etc., but not any third-party apps that I have installed.

Thank you for the suggestion, but unfortunately it does not help.

Firstly, I am running Catalina v10.15. When I try to open a third-party application such as Typora, I only get the following example [/System/Volumes/Data/Applications/Typora.app] Alfred 4 will not show any third-party application in the results. The built-in apps that I have tried do show but way down the list, the top item being as above. I have checked the Alfred website and I do have a valid Powerpack license for Alfred v4, and I have checked Spotlight and it finds the application in /Applications folder without any problem. However, I did migrate my Alfred v3 settings when installing v4, if this has any relevance to my problem. Under search scope the MacOS applications folder is checked, and I added my Applications folder to the list to be searched, just in case. Launching the app using either the Finder or using the above available command once, does not change anything. I have typed Reload into Alfred but, again, this does not solve the problem. Any further ideas would be much appreciated.
