Version 8 (8.2.23346.13002, 2023-12-12) update issue

Is anyone having problems with having everything disappear and only the viewport is showing? I updated it just now to version 8 (8.2.23346.13002, 2023-12-12) MAC and nothing can be seen except the viewport window. no toolbars, sidebars, or command line…
