Popup message saying “A toolbar is already hidden on this side of your screen. You can have only one auto-hide toolbar per side.” and an ok button.

Windows 11 occassionally shows me this message after unlocking my laptop when I have a second monitor connected. Not sure why it does this, when I do nothing except lock my laptop. Then it undoes my “auto-hide toolbar” option and I have to enable it again.

And this all worked properly until Windows 11.
