windows 11 preview from taskbar showing on the left

Hi there, I feel your pain, this is a bug, I have the same behavior.

One hack that I use to relief the pain is restart the 'explorer.exe' application, that did the trick for me.

You have different alternatives to do that, you could do it through a terminal or from the task manager.

I will give you the steps for the second option:

1. open task manager
2. you need an explorer window open, if you don't, you could open one like this, 'File'->'Run new task'  fill the dialog with 'explorer' then click 'ok', or just use the hotkey 'win+e'
3. now right click on the explorer application listed in the Process tab, and select 'Restart'.
   
   The explorer process manage a lot more than the file explorer, so after you restart all the desktop UI manager will be restarted. That solved for me the issue. 
   I repeat this from now and then when the bug reappears.
   
   Good luck
