Separate an app problem from a device problem
Open a different app from the home screen. If it works, return to the affected app and note when it closes. A crash before a profile loads points to a different stage than an error after selecting a particular video. Check for available app and system updates, then repeat the same action.
Preserve your setup
Check the intended app store listing and note the publisher before uninstalling anything. Some devices expose a data clear under the Apps section. That operation can remove player state. Have the restoration method available, then apply it only to the affected app.
What to share
Give the full device model, Google TV software version, player version and the screen where the crash occurs. If all apps have trouble, follow device-level network, update and restart checks first.
