First, could you let me know if you've done any troubleshooting steps already? For example, have you tried restarting your Samsung TV, or maybe reinstalling the Fox Nation app? Knowing what you've attempted will help me guide you more effectively.

In the meantime, I'll prepare a list of common fixes that might help with the crashing issue:

1. Restart Your Samsung TV: This can sometimes resolve temporary glitches. Simply unplug the TV for about 60 seconds, then plug it back in.

2. Update the TV’s Software: Make sure your Samsung TV is running the latest software. You can check this in the TV's settings under "Support" > "Software Update."

3. Reinstall the Fox Nation App: If you haven't tried this yet, uninstall the app and then reinstall it from the Samsung App Store. This can help with any corrupted files that may be causing crashes.

4. Check Your Internet Connection: Ensure your TV has a stable internet connection. You can do this by checking other streaming apps to see if they work properly.

5. Clear App Cache: If your TV allows it, clearing the app's cache can help. Go to Settings > Apps > Fox Nation and see if you can clear cache/data.
