Leave insider preview via another account

This is most likely a problem with a preview update. Some users have had the problem be fixed after a power cycle (unplug for 30 seconds) one or a few times.

Another solution would be to leave the insiders program (via opting out in the preview app) and wait until your xbox gets the public update back to see if that fixed it.

If this isn't a preview update issue I have no idea. You could try the Xbox (beta) app from the store to see if it's the app's problem.

What preview are you in?

Using the Insider hub >Manage should state what you're enrolled in.

Most of the time a factory refresh is required when leaving, changing a preview ring or leaving Insiders altogether. You will need the account details and passwords for all accounts that are set up on the console now to set the console back up after the factory refresh. Your games and apps shouldn't be affected unless you decide to do a complete factory refresh and delete everything. Xbox Insider FAQ

Did you create a bug report for the issue? This won’t resolve it right away, but it would help correct it in the next software update in a week or so.

As it’s something in the Xbox Insider preview, you would need to leave/opt out of it for the console to display normal text. Please see the official Xbox Insider Programme FAQ for the steps - specifically:

‘How to remove a single console from the Xbox Update Preview programme ‘ or if you want to leave the program completely, ‘I no longer wish to participate in the Xbox Update Preview or in another playtest or preview. How can I stop participating? ‘

Resetting your console may also help.

It should be back to normal once you’re on a public (non-Insider) OS version. If there’s still no difference, let me know and I’ll ask the team to see if there’s anything else you can do.

Here's a question...Why are Ambassadors advising to use OSU's prior to determining if the gamer is in the Insiders preview program?

The Insider MUST leave the preview before even attempting to use OSU's.

Are you still in the insider program? Your best bet would be to use the insider app and leave.

Follow these steps to leave it.
