Since "upgrading" to Windows 11 every time I start the computer and log in nothing appears in my task bar. I have to sign out (not restart) and log back in then the icons populate properly. The other issue isn't so much of an error but apparently complete lack of foresight... I can duplicate the task bar on all monitors, problem is that only the main will show the clock and any icons on the right hand corner... so any program that runs in on the main monitor (full screen) covers up the clock, etc!!!
I have the exact same problem. Everything was fine for a few weeks after upgraded to Windows 11, and suddently I started getting empty task bar, and I have to log out and log in again to find my taskbar icons. Any update on this?
