Now I'm @work, my PC has Windows 7 so I can't try. You can make those quick tests:
1) Reboot PC, don't open edge browser and create an empty excel file on the desktop (right-click, new excel file). Then launch it and see if it starts quickly or not.
2) Create new account like you did before. DO NOT OPEN EDGE. Reboot. Never open Edge and try. Reboot and try again.
Maybe Edge related...
