TKaraokeUSB on Android TV 10 or newer
Build 152 has been released to the Google Store. You will need this build or newer if you upgraded your device to Android 10 or newer. Google introduced a more restrictive hard drive accessing mode starting in Android 10.
The MiBox and the Shield are still on Android TV 9 but some Sony TVs have been upgraded to Android 10 and newer models have been upgraded to Android 11. Pretty soon, the Mibox and Shield will upgrade to Android 11.
My Shield Pro got updated and of course things got messed up (TKaraoke, Plex, etc..)
