Hey Andrew - what a quick turnaround. I removed any alfred accessibility references from settings, launched the beta from the download in your post, followed your directions and I am back in business. Thank you very much!
Unfortunately still a problem for me. On High Sierra I was fine and then it quit working after working with the beta (and I understand this is beta). My symptoms are the same.
- I've unchecked, removed the items from security menu and had them added back on recheck.
- I've tried a different (new) login account.
None of these worked for me. Oddly I have Magnet as well and that one seems to be functioning fine.
Alfred Build 922 - I can type "snip <snippet>" into alfred and it recognizes it and will paste it into underlying app.
