Here is a video about an error that the game produces when starting it up.
https://youtu.be/sO8Vspvt7CA
The game is freshly downloaded and installed from the Google Play store.
I had no other processes running nor did I use any plugins. The Game is freshly installed, as I said.
I am using an Nvidia Shield TV and the operating system is Nvidia Shield experience based on Android 11.
The game was running fine until two days ago. I did not alter any permissions given to the APK.
My location is Bavaria in Germany.

I hope you can figure out what the problem is with that information. Thank you in advance.

I don't have this device, but searching around it appears that Nvidia Shield updates can interfere with the functionality of apps.

1) Reset the Shield.

2) Failing that, uninstall / reinstall Vendetta

3) Failing that go to: Settings -> Apps - Vendetta -> Permissions -> Files and Media and select Allow all the time.

Force close Vendetta if it's open then reopen after applying

Also check that you have enough storage space available. 50-100 megs of available space should be sufficient.

We tested it with a Shield TV and had no problems with the update or running the game.
