What is the point of your ticket system if you keep telling people that there is already a "duplicate" ticket opened, when that ticket is already marked as resolved with no actual resolution. End users pointing out a "work around" by disabling their ad blocker, is NOT a resolution for the issue. The app needs another fix applied.

The ad blocker on your Eero router is most likely causing the issue as it seems there is a bug with this patch when it comes to ad blockers. Turn that off and it should work, although I would prefer to keep my ad blocker running.
Turn off your ad blocker and try again. That resolved the crashing issue for me.
Hopefully this helps someone, but to add to the ad blocker issue, I found that after creating a rule in my ad blocker to allow vortex.data.microsoft.com the crashing issue was resolved. Hopefully someone can chime in as to exactly why this connection is required when this issue just started with 1.20.71.
