Hazel Freezes my iMac

I enjoy the concept of Hazel and planned to buy it until I used it with Catalina osx. In Rule making and selection of folders it continues to freeze my computer on a regular basis. When I am about to complete the Rule, I notice that the computer stops responding, and my only course of action is to Force Close the app. Even if I am successful in completing the Rule and closing the app, it appears that some of the rules and resulting Actions just don't work. Hopefully, when a new version is available, the app will be effective, since the concept is interesting.
