If I use "Lock", it simply does nothing. It can "Sleep"
I saw the previous bug report and removed accessibility permissions and added them back. It got rid of a "beep" but it still doesn't work.
I can "Lock Screen" from the Apple menu
I am able to reproduce it.
Using Alfred 4.5 [1253]
macOS Big Sur 11.4
What other information would be helpful?
Thanks in advance,
Alan
