Attempt to disconnect a nonexistent connection from 'root:<Window#32010929360>'. Signal: 'focus_entered', callable: ''.

Might be a duplicate, but exiting the main menu sometimes causes:

USER ERROR: Attempt to disconnect a nonexistent connection from 'root:<Window#32010929360>'. Signal: 'focus_entered', callable: ''.
   at: _disconnect (core/object/object.cpp:1420)

I encountered this issue too.
I'll try to see if I can make a repro, for now it's quite random for me.

I can reliably reproduce this by interacting with an option button in the options menu.

The error here is the same as in godotengine/godot#89657 (with the focus_entered and tree_exited signals on the root window) so I believe that this is the underlying cause.

That's very interesting if it is a Godot engine bug and not something we have caused. I posted in that issue me just testing and re-triggering the issue to make sure the issue isn't closed as Godot 4.3 still definitely has the bug. I'll unmark this from our milestones as we can't do much to impact when Godot engine fixes this.
