Hazel problem - freezing when adding new folders

Hazel keeps freezing for me whenever I try to add a new folder for it to sort. Is anyone else having this problem? I haven’t found a way to fix it yet…

Are you running Catalina? The developer has noted there are stability issues on the not yet released OS.

Ah, that would explain it. The beta has been working so well recently (yes, I’m lucky) that I half forgot I was running it!
