Google slides has stopped working in Safari on Mac

Up until today Google slides worked flawlessly in Safari. Today on same iMAC with macOS Catalina 10.15.7 (19H2026)I cannot get the home page of Google Slides to load. Keeps giving the error message "Home screen is temporarily unavailable. Try to load it again or send an error report." But there is no way to send an error report and when I hit Reload the same loop occurs. Works fine in Chrome. What's up?!?!?
