When I opened the exe file for a second time (to disable it), my entire desktop turned black. But I think it's just a window, because when I press that button on the right of the taskbar that minimizes all windows, my desktop is back to normal. I have no idea how to fix it, I've tried closing some exe files with Task Manager that I thought might be causing it, but nothing worked. I'm pretty sure it's not a different app causing this, because it happened right after I opened Win11DisableOrRestoreRoundedCorners.exe.
