The wrong window sometimes closes when using the close window keyboard shortcut in Anki for Mac Version ⁨24.11 (87ccd24)⁩.
Repro steps:

Open the Anki application.
In the main (User 1) window, click Add (to open the Add window) and then click Browse (to open the Browse window).
Click the title bar of the Add window, to focus it.
Press command-w.

Expected: the Add window should close, since it’s focused.
Actual: the Browse window closes.

This happens because the Browse screen is a main window and has its own menubar, complete with Close action. The add window is not, so the browse menubar is retained. We could fix this by making close act on the currently-active window, or removing it from the menubar.
