Every tab is titled "Untitled" and displays blank

Latest Edge Canary version...sorry I can't tell you which because no page will render in Chromium version of Edge.  Not any external or internal website, not even the help or settings pages.  Ever page opens as "untititled" and is a complete blank  Have uninstalled Canary build and reinstalled (11/22/2019).  Have cleared all internet settings, favorites, and etc.  The only thing that has worked was to add "-no-sandbox" to the command line to launch it and then pages render normally, but I get a warning that this is an unsupported switch and may cause stability and security problems.  Any thoughts?
