Description
Opening of files given by content:// Uri:
QFile file("content://eu.basicairdata.graziano.gpslogger.fileprovider/cache/Tracks/20240117-192053.gpx");
file.open(QFile::ReadOnly);
is broken in Qt 6.6 on Android. This is a regression to Qt 6.4.0 where opening of such file names worked fine. Trying to open such file ends with the following error log stream:

Note, that this is not a permission issue as it may look from the log as the file is perfectly accessible from java+, but opening it using Qt fails.
This is a major issue as on newer Android versions this is the only way how to work with files received from other applications on Android.
+ You can test that by modifying the intentPath() function in GPXSee which is the application used to trigger the bug
