Same or similar problem here with MS Edge. When I open Edge most times, (not always) in the top left tab it goes directly to "go.microsoft.com" instead of opening my home page. Edge then just sits there spinning the MS 6 circular dots forever. I have to close the browser and open it again; if I'm lucky, my home page opens immediately.
Fire Fox works just fine everytime, opens home page immediately no problems. I wonder if it may be looking for a MS account, which I don't have.
