Microsoft To Do Online version will not show All - it goes to blank screen

I am using Microsoft Edge on Windows 10 - when I use the online To Do, if I click on All, the page goes blank and freezes.  This was working fine yesterday.  My other Smart Groups work fine.

On the desktop version, I can see everything under All (but the app crashes for a different reason - Shared Files) : )

I have closed browser, on and off VPN, closed outlook and done syncs.

Any other ideas?  Thanks braintrust!
