i found the fix for my Video Screenshots issue. after posting to the /zwift Reddit group, a user advised editing the prefs.xml file for <video_capture_enabled>1</video_capture_enabled> and setting that to 0. after doing that i launched the app and confirmed in Settings that Video Screenshot was now set to Disabled. i then backed out to the Trash Can/Save screen and selected the Trash Can and it worked taking me to main options screen where i could then Exit. hope this helps others!
also, note that the Video Screenshots option was pushed out to certain processor levels, not necessarily and OS version issue. the processors are listed in a Zwift Insider article and i was able to confirm my affected laptop has a processor in that list.
