MuseScore [MU4 Issue] Mac "open -a ...mscore filename.ext" ignores file

Describe the bug In previous versions of MuseScore, Mac users could open MuseScore and show a particular file with:

open -a "/Applications/MuseScore 3.app" filename.musicxml (or .mscz, etc.)

In MuseScore 4, if MuseScore is not already opened, then the file is ignored and only the New & recent files browser shows up. (Same if /Contents/MacOS/mscore is appended)

The command "/Applications/MuseScore 4.app/Contents/MacOS/mscore" filename.musicxml with the full path to mscore without the open -a works, but this takes control of the terminal, prints debug information, crashes the program upon Ctrl-C, etc.

If MuseScore 4 is already open, the open command works as expected.

To Reproduce Steps to reproduce the behavior:

Create a mscz file called t1.mscz on Desktop
Be sure to close MuseScore 4 completely
Open terminal
Run cd ~/Desktop
Run open -a "/Applications/MuseScore 4.app" t1.mscz
See New & Recent screen rather than the score. (the bug)
Without closing MuseScore 4, go to Terminal
Run open -a "/Applications/MuseScore 4.app" t1.mscz again
t1.mscz is properly shown in MuseScore 4

Expected behavior The effect of step 9 (seeing the score) should have already happened at step 6

Platform information

macOS 12.6
MuseScore 4.0.0.223472200 without MuseHub

Additional context Noticed while checking music21 for MuseScore 4 compatibility. Without this function, score.show() will not work with MuseScore 4 configured as the default MusicXML reader.
