Can't open Mixer in Musescore
I am using the Flathub version of Musescore (I use a SteamDeck as my desktop, which is ArchLinux based)
Every since Musescore 4.4, I cannot open the Mixer, Piano Keyboard, and other windows.
I also can not see the window for Percussion Inputs, so I can't make parts for Drumkit.
I've tried resetting to factory settings and reinstalling, but nothing has worked.
