Describe the bug
With the launch on login option checked, eqmac starts with an empty window (on system startup only), which after a few seconds, the windows close and the status bar icon appears.

Steps to Reproduce
Steps to reproduce the behavior (feel free to change the placeholder as you need):

1. Mark 'Launch on login' option
2. Shut down the system
3. Turn on the system
4. An empty window is shown very briefly, then it closes and the status bar icon is shown.

Expected behavior
This transition with the window opening in the middle of the system and then immediately closing is a little annoying. I would just like to know if it is possible to start the app more quietly (without the empty window appearing and closing).

Setup information:

• Audio device used for playback: Macbook speaker
• Audio transmission interface: built-in
• macOS Version: 13.2.1
• eqMac Version 1.7.7
• eqMac UI Version 4.6.1
