@deanishe I ran what you mention in the terminal but did not make any changes.

@Andrew I did what you tell me and the result is as follows:

Is possible recreate this metadata?

No, i’m using the last versión from website.

you should restart system and you can have a try

I did it rebooted and uninstalled completely and then i installed Alfred and the problem persists.

I recently updated my mac to Catalina 10.15.5 (latest version) and from that moment Alfred does not show the new installed applications, for this reason I cleaned the cache and metadata, now Alfred does not show any applications except for the system ones, but Spotlight shows the  applications without problems.
