Problem under Catalina: Trash and system preferences freese

Hi, I downloaded Catalina a few days ago and since experience some issues with Hazel:
First, it seems not longer possible to move files to trash, as the "Trash" Folder does not longer exist (for Hazel).
Second, and this bothers me more: Every time I open Hazel, the system preference window freezes after some clicks and I have to restart my Mac. As the system preferences are open and obviously somehow running, this can only be done by holding the start-button and doing a dirty restart of the machine.
Is there any workaround for this (probably known) problem?
Thank you!
