Trouble updating and opening the Microsoft Store

Hello LLAMPOL,

Thank you for posting here on the Xbox forums. I recommend performing a
soft factory reset. This will reset the operating system and
delete all potentially corrupted data without deleting your games or apps. You will have to re-sign into your account, so make sure you know the email and password before performing this step. This will also reset the
home Xbox settings.



Please note that if you are part of the preview program, you should
report this issue through the insider hub, as well as to the

insider reddit instead of doing the factory reset.



If you’re ready to reset your console to the factory default settings, follow these steps:

1. Press the Xbox button to open the guide.
2. Select System > Settings > System > Console info.
3. Select Reset console.
4. On the Reset your console? screen, select
   reset and keep my games and apps

Check this support link for a possible solution: https://support.xbox.com/en-US/xbox-360/errors/error-code-80070003

Already did all the steps and nothing worked, and i also noticed that the only solution to that error code is for Xbox 360, not One like my console, but thanks for your time.

If you are having trouble installing/opening the app use the microsoft store

I have troubles as well on Microsoft Store. The game was updated correctly on Steam.
