How to close "Unity Editor is up to date" window.

When I open a unity project, this window appears.
And I can’t close it. Can someone tell me how to close this?

@iusenanayake I had this same problem, and I just had to reset my layout. It should also work if you set your layout to a different layout. Hope this helps!

Window>Panels>Close all floating panels.
The bug is quite strange tho.
