The transcription hotkey doesn't work anymore after some time

After some time (like 5 hours, but could not figure out how much) or maybe some particular event from my computer, I loose the ability to launch the transcription ("transcription hotkey”), nothing happens anymore when I press the hotkey, the bar with the wave doesn’t show up anymore (I use control+shift, but I tried other combination, it has the same problem).

Vowen is still running, as I see it in the bar, and I can open the settings window without any problem. Even if I change the hotkey, I can’t make it work anymore. The only solution I found is to stop and start the application.

Running latest version (0.1.9), on MacOS Tahoe 26.2.
