Hi, new here but a long time Alfred fan. Keep up the great work!
I was able to fix this by removing and re-adding Alfred from the Accessibility panel.
Steps:
Go to System Preferences
Open Security & Privacy
Go to Accessibility
Click the lock
Select Alfred 4
Click the minus
Drag the Alfred 4 application from your Applications Folder onto the Privacy panel and make sure the checkbox is checked.
Hope this helps someone!
