Anyone else getting an error that says "We're sorry something unexpected happened" upon...

A hard reboot should fix this. Hold down the power button on your console for 10 seconds until it fully powers off. Then unplug the power cable for 5 minutes. When you boot it back up the system cache will be totally cleared, and all of your apps and games
will have a clean syatem to boot up on. Also, if you're an insider and using the twitch beta app, definitely consider reporting this as feedback by holding down your guidd button and selecting "report a problem". All the best, cheers!

If the above does not work, remove the app then power cycle the console again to clear the cache and then reinstall the app

Hello Titantheeditor,

Thank you for posting on the Xbox forums. We understand that the Twitch App is not launching, and it is providing you with an error message. Are you using an Xbox One or Xbox 360? If you are using an Xbox One; we recommend

power cycling the console by holding down the power button on the console for ten seconds. We have a support article which provides troubleshooting steps for an

I keep getting....

WE'RE SORRY!

AN UNEXPECTED PROBLEM HAS OCCURED.

it told me that "Something unexpected happened" and I got the error code 0x0000001. I tried restarting my pc and making sure it is up to date (which it is) but nothing has helped. Does anyone know why I am getting this error code?

I'm getting a similar result trying to install Gears 5. Same error.
