[MU4 Issue] MuseScore quits instead of just closing score

[HemantAntony]

Describe the bug
When you press Ctrl + W to close the open score, it

To Reproduce
Steps to reproduce the behavior:

1. Open any score
2. Press Ctrl + W
3. MuseScore quits

Expected behavior
Only the score should close instead of the whole app

Platform information

• OS: Ubuntu 22.04 LTS

Additional context
For the Devs, this problem occurs because there is more than one instance of the app open. Hence quitApp becomes true, hencing forcing MU4 to quit. I would've attempted to fix this. But this lead to bunch of things about IpcSocket (It sounds too complicated :) )

Also, if no one can reproduce this, ask for any other info you might need

[HemantAntony]

This might be related to #13698. However, in that issue it states that the issue is a crash. Hence I thought it might be a different issue. But they both do look similar

[Eism]

@HemantAntony
Yes, it's the same bug(#13698)
Please check the build from #13774

[Eism]

Ah, I missed additional information.

For the Devs, this problem occurs because there is more than one instance of the app open.

This is expected behaviour. See #9966

[HemantAntony]

@Eism but that behaviour is only when there are more than 1 projects open. This issue occurs when only one project is open. So MuseScore should not close

The bug is that there are two app instances in the code when in reality there is only one

[Eism]

@HemantAntony make sure you have only one instance open.
I can't reproduce

[HemantAntony]

I only do have one instance open

If no one can reproduce, I guess I will try to figure out what the problem is (emphasis on try :) )

[AntonioBL]

Ciao.
I managed to reproduce it most of times with these steps:
1- Open MuseScore
2- Open a recent score ("score1") from the dashboard
3- Open another recent score ("score2") from the "recent files" menu
4- close score2 with Ctrl + w
5- close score1 with Ctrl + w -> MuseScore quits
In case, repeat the previous steps (i.e. open two scores from recent file menu and close one after the other)

Linux Mint 20.3, Arch.: x86_64, MuseScore version (64-bit): 4.0.0-3239707478, revision: github-musescore-musescore-2d8a581

[HemantAntony]

@AntonioBL Hello, that is sadly(?) another issue #10399

[DmitryArefiev]

@HemantAntony Can you do a factory reset, restart OS and then try again using build from #13774 ?

Maybe that helps..

[HemantAntony]

When I test this issue after booting from a LiveUSB, this doesn't occur. Hence, likely something to do with my system :(

Happens again in latest nightly.

@DmitryArefiev I tried build You sent me also with factory reset.

Same result - after closing score, MU quits.
