How do I force the multi-monitor taskbar to close?
Originally the software was working fine, but yesterday I purchased a license for the STEAM version, reinstalled the software according to the STEAM process and shut down the computer, and then after rebooting, I found that the multi-monitor taskbar could not be substantially closed.
I only want to display the taskbar on the main screen, and hide the taskbar on all the other sub-screens, and all I need to do is to remove the checkbox “Enable taskbar on each monitor” in the “Taskbar” section of the software, but now this checkbox is empty. “Enable taskbar on each monitor” in the ‘Taskbar’ section of the software, but now the checkbox is empty, and there is still a taskbar on each monitor.
I tried to re-select the above option, and turn off the checkbox again to make it effective, and then this error report popped up (see attached screenshot), if I clicked on “Disable the WINDOWS taskbar (see attached screenshot)”, I can't disable it substantially. If I click on “Disable WINDOWS taskbar (recommended)”, the error report will pop up again and again, if I click on “Disable DISPLAYFUSION taskbar”, although it does not report an error, but any modification does not take effect, and all monitors still have the taskbar.

I don't want to analyze or tweak it in a complicated way, I just need to disable the taskbars other than the home screen, please tell me how to do it. Is there a place in the “Advanced Settings” to enforce this?

If you only need the taskbar on the main monitor, you'll need to disable DisplayFusion taskbar support, and change a Windows setting to not show it on other displays

On DisplayFusion settings, under Taskbar, uncheck the first option "Enable Multi-Monitor Taskbars"

On Windows settings, go to Personalization, Taskbar, open Taskbar Behaviors, and uncheck "Show my taskbar on all displays"
