This update doesn't solve issue of CR clarity & texture (& often other adjustments) freezing for 30 sec, and sometimes crashing the system - losing all work on the file. Usually a frozen beach ball comes with the freeze. This occurs while browsing in Bridge, then opening the file in CR. Once in full PS, there are no issues. This is ONLY OCCURING IN CAMERA RAW which appears to be unstable on Catalina 10.15.7.
I've tried altering the graphics card setting in Prefs - Performance to "off" but the issue persists.
