Hi

Can you please follow the
Troubleshoot Blank TV screen guide here and select the troubleshooting for your screen is blank after you install an update and this will hopefully help to resolve your issue.

if you using the disc then install but don't accept the update, after it is installed then launch the game and accept the update

So the best thing to do with a disk game is to download the game offline then install the update. Go to settings, network, and go offline. Once the download finishes, go back online for it to install the update.

if you want your games to update while the console is off you need to put it in "Instant On" mode.

After the Verifying stage of the update the console will shut down and restart to Apply the update.

On a Series X you should see the Xbox button flash about 5-6 times as it restarts before the screen will go blank and then a few seconds later the console will restart so the update can be Applied.

Don't interrupt this process by manually restarting the console. If you do interrupt this process the update will download and verify again, and then do a automatic restart so it can Apply the update. Be patient while it completes and returns to the sign-in screen.
