Hosted feature service attribute table fails to open

[ByronTsang]

A hosted feature service won't open it's attribute table, claiming an "external component has thrown an exception".  I'm able to view and edit attribute data in the Attributes pane, but it won't let me view the table.  Thoughts??

There's probably a connection issue between Pro and the portal. Try signing out and restarting ArcGIS Pro.
