I've been seeing this message too "A toolbar is already hidden on the side of the screen". I can't open any toolbar on the side of any screen.
Came here looking for a fix to the auto-hide task bar always being shut off.
Window 11 taskbar auto-hide turning off

I switched to Windows 11 a few weeks ago, and ever since then, the taskbar auto-hide quits working when the computer comes out of Sleep mode. I have to be away from the computer for a while before it will happen, and I believe it has something to do with me running dual monitors. When I wake my computer, my secondary monitor appears to come up faster than my primary by just a fraction. Once my primary is on, there is a message saying something about the taskbar already being hidden (I think) and the taskbar on my primary monitor has the taskbar up. When I go to Taskbar Behaviors, 'Automatically hide the taskbar' is no longer checked. I'll select it again, and it will work fine until the system goes back into Sleep mode for a while, again.

2022-03-14T08:48:27+00:00 Sorry guys but it's not just a Win11 issue. I am running Win10 have exactly the same issues - as I am sure both OS share some code likely to be due to a change in that. another clue to MS - anyone listening? When I get this error message the taskbar's autohide stops working. Is there another clue in that called 'toobar' in this error message?
How do you get a response from MS?

2022-03-11T14:25:43+00:00 My PC had Win 8, which Microsoft upgraded to Win 10. I then ran Win 10, with no taskbar auto-hide issues from it's 1st version through the last, before the Win 11 upgrade was offered. Then, and only then, in Win 11, I started having issues with the taskbar auto-hide setting reverting to "off" automatically. Now that I reverted to Win 10, I have no taskbar auto-hide issues! The switch from Win 11 to Win 10 was painless & quick!

2022-03-11T13:08:02+00:00 I had the problem with Win 10 before too. This feature was working quite well some years ago on the first releases of Win 10., then the engineers of Microsoft started to improve...
