Unity Editor shows additional ghost window in taskbar

Since today, I have the problem that when I start Unity through the Hub, Unity not only shows the editor in the Windows taskbar but also a “ghost window” that is completely empty in the taskbar preview.

When I hover the mouse over it, a blank Windows Console/Terminal window appears.

However, I cannot focus on the “ghost window.” If I close the ghost window, the Unity editor also shuts down. This problem has never existed for me before. What could be the reason for this?

It turns out the issue is caused by having a newer version of Unity installed alongside the older one.

When I install Unity versions 6000.0.14, 6000.0.15, 6000.0.16, or 6000.0.17 and then open a project in Unity 6000.0.4, it brings up an extra ghost window.

However, when I uninstall the newer versions, the ghost window disappears from the older Unity version. :man_shrugging:
