Zoom Timer app no longer works

[RebeccaBee]

The Zoom Timer app no longer works for me as of yesterday. I have never had trouble with it before. I have uninstalled and reinstalled both the Zoom app and the Timer app within Zoom, and restarted my computer. The problem remains. When I open the app, the Timer logo flashes briefly and then I get a black screen instead of the timer. I am running macOS Catalina 10.15.7 and Zoom version 6.2.10
