Input switching no longer working

[greatestradioshow]

Hi all,

I have a Xiaomi Mi Smart TV 4S (MSSP3).

After installing Flauncher and disabling the default launcher, I'm no longer able to select/switch the input/source.

I performed the following to commands successfully:
adb shell pm disable-user --user 0 com.google.android.tvlauncher
adb shell pm disable-user --user 0 com.google.android.tungsten.setupwraith

Is this expected, or how can I make the input selector/switcher work again?

Thanks.
