How are you running it in steam deck, as a windows emulation or via a Linux shell?

If via windows, you may be able to reset it back to default settings if you wipe your player data (this may also wipe your progress). You can find it here:

AppData Folder:

1. Open File Explorer.
2. Enter %AppData% in the address bar to navigate to C:\Users\[YourUsername]\AppData\Roaming.
3. Navigate to ..\LocalLow for Unity game data.
