I've had a ticket open with my IT for months with no resolution. Our IT say they have me and another new member configured like all the others but ours get the white screen, while the older members get proper access. It's apparent they don't (or you don't) talk to each other on this issue. Login screen looks like broken old BBS system with text displayed. Fill in the login credentials NEXT and password then get the white screen. Windows 10 Pro 22H2 12th Gen Intel(R) Core(TM) i7-1270P 2.20 GHz. Tried using Edge, Chrome, and Firefox browsers. Cache cleared. Since I don't have admin access to this machine I'm limited in what I can configure/change. I wish you posted the resolutions of the many users who have reported this problem so one could try to get this working.
