Hi Vero. It didn't work in any app. Unchecking, rebooting, and rechecking didn't help. But, you gave me an idea that did work, so I'll write it here for future reference. 
 
I quit Alfred, then opened the terminal and typed
 
tccutil reset All com.runningwithcrayons.Alfred;  
This forces a reset of all permissions. Then I reloaded Alfred and granted permissions anew. And it worked! So for anyone else that runs into this problem, try the more drastic permissions reset in terminal. 
 
Edit: hah, I thought I was being clever by figuring this out myself, but I see this step is listed at the bottom of the page you linked. So, it worked! 😃 Thank you.

@atsumori Which app(s) are you trying to paste into? If you use TextEdit, do you see Alfred paste normally?
 
Have you checked that Accessibility is granted to Alfred? Have you tried removing and re-adding Alfred to ensure macOS is "nudged" into seeing that you've granted it.
