Yes -- it's a weird one. My studio system (Win 11) updated just fine. It's my office HP (Win10) that did the funky thing. Just to check I updated my Lenovo laptop (Win10) which hadn't been updated in a year or two, and it updated just fine. Perhaps I had a misfire when I updated the office HP.
After my update to 23.09 (a few days ago), this happens with my start screen. Everything else seems to work properly, it's just the link to an URL. FYI and any suggestions on how to get the start screen back. Thanks in advance.
