[2021] Game suddenly won't start on my xb one [... Conan took too long to start (0x8027025a)]

Hello @hal9000, we’d suggest that you first ensure that your save is stored on the XBOX cloud, before trying to follow the steps below:

• Reset the console cache by holding the power button for about 10 seconds until the console powers off, then disconnecting it from the power outlet for a couple of minutes.

• If the issue persists, try to perform a soft factory reset while keeping games and apps.

• Should you still have trouble loading into the game, please try to do a full reinstall of the game.

Please let us know if any of these steps help.
