An image showing that the file picker filter is set to "Audio files )"

SUMMARY
KAlarm play audio feature stopped working after I upgraded to KDE Plasma 6. When I try to re-select the audio file I found that the Choose Sound File (File Picker) "Filter" section contains "Audio files )", which result in no files being visible.


STEPS TO REPRODUCE
1. Create an audio alarm
2. Click the choose audio file button to open the choose sound file (file picker)
3. Observe that you can't see any files at all because the filter is set up "Audio files )"
4. Change the filter to all files, then set it to any audio files.
5. Wait for the alarm to happen

OBSERVED RESULT
- When I click the choose audio file button, I can't see any audio file
- No sound was played when the alarm got triggered

EXPECTED RESULT
- When I click the choose audio file button, I can see all audio file
- I hear a sound playing when the alarm got trigger
