Taskbar Icons disappearing

Why are the icons on taskbar keep disappearing when Taskbar set to HIDE AUTOMATICALLY? All is fine if taskbar is not set to hide. This problem appeared only after having installed Build 25247...
Is there a fix for this?????

OS Build?..... I am running Version 22H2 (OS Build 22621.1020) and this morning my hidden icons and clock were gone. If I clicked on the Start button, the menu was blank but when you did a mouse-over you could see where everything was supposed to be. I signed out and back in and everything looks fine. I am about to run SFC /SCANNOW and DISM to see if any files are corrupted or missing. Maybe you should do the same. Here is a link if you don't know how.
