This error occurs when you take the Apple TV Box out of sleep mode and wipe it on the remote when it boots up. This causes errors in several apps due to the operating system of the Apple TV Box, so unfortunately we can't do anything about it.
If you don't press or wipe anything on the remote control during startup after sleep mode, you can avoid the error so that it doesn't occur in the first place.
Fortunately, should you ever experience it, it's easy to fix:
You press the screen button on the Apple TV remote twice and wipe the Teleboy App upwards to close it. You can then restart the app. Everything will work again as usual.
