Current Behavior

I've installed Spotube from Flathub. The first time I launch the program it works just fine but the second time I do it opens up to just a transparent window (I only see the window borders). The logs report:

[ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: FileSystemException: lock failed, path = '/home/bart/.var/app/com.github.KRTirtho.Spotube/data/spotube/oss.krtirtho.spotube.cache.queries.lock' (OS Error: Resource temporarily unavailable, errno = 11)

Expected Behavior

Spotube to always launch like it did the first time, without a transparent window.

Steps to reproduce

1. Install from Flathub
2. Open the app once
3. Close the application
4. Open the app again

Operating System

Linux

Spotube version

3.2.0

Installation source

Ah, found the problem. Quitting the application doesn't actually quit it properly. There is still a "icon" in the system tray (using KDE Plasma). Well icon is not really accurate, it's just an empty spot, no icon is actually shown. But that is blocking the launching of the application. If I kill the still running application (sending SIGKILL) then I can launch it up fine again.

Same as #768
