Record the exact moment of failure
Test one problematic game and one that usually works. Write down the error text and the stage: start, menu, connection or continuation of the session. Specify your account, purchase method, and subscription activity if the game is available through it. If access to the subscription catalogue has disappeared, installing files does not confirm the right to run. For network failures, separately check the messages from the game developer himself.
Check console updates
The 2K general instructions for Xbox One and Series X|S indicate the path Profile & system, Settings, System, Updates. Connect your console to the Internet and see if an update is available. Complete the update as usual, then test the same game again. Also check for updates to the game itself. When comparing, keep the same account and launch method so as not to mix different reasons.
When to check Quick Resume
For some online games, 2K recommends checking Quick Resume when returning to a session fails. Compare the continuation of a paused game with a new normal launch. If the problem appears only during recovery, look at the current Quick Resume settings of the selected game and the recommendations of its developer. Don't assume that your entire console is broken based on one failed return to an online match.
Network, reinstallation and saving
If an error occurs when connecting, check the network through Settings, General, Network settings and compare the status of the game service. Reinstallation takes more time, so proceed to it after simple checks and checking the instructions for the specific game. Before doing this, make sure you understand the state of saves and synchronization. For support, please prepare the error code, game version and the results of the previous steps. This is more useful than repeating one unsuccessful launch.
