I'm having the same problem described here. Since upgrading to Big Sur, I noticed that new applications were not appearing in Alfred. I clicked the button to have Alfred rebuild the application cache, and now no applications show up in Alfred.
I ran the file metadata troubleshooting on an application and it returned similar results to the one posted above.
Starting Diagnostics...

Check mdls file metadata...
❌ macOS metadata missing essential items

❌ Troubleshooting failed
I've triggered a rebuild of the macOS Metadata, I've tried toggling the Full Disk Access permission, but nothing has improved the situation.
Is there anything else I can try that doesn't involve wiping my hard drive and starting over fresh?
