I installed the KB5022913 on 1.39.1. There were no system tray icons or clock visible. Also there was a light line across the top of the taskbar, and where the search icon is (even when removed!).
Went back via a disk image to before KB5022913 was installed.
I then installed the beta 1.4 279 and then installed KB5022913. The problems I had (described above) returned, so it seems to me that the 1.4 beta does not solve the problems with this Windows 11 update.
I have now returned via a disk image to before KB5022913 and using 1.39.1.
