[WEB-1345] Don't see login screen due to Uncaught Invariant Violation: Minified React error #31

I have following errors in console. It happens in Incognito too, so it's not due to extensions. The login screen is just as in screenshot, there is no login fields. Works fine in Firefox. Google Chrome 75.0.3770.100
