Windows 10: Error code 0xc0000420

I used to be able to play Forza Horizon 5 on my computer using the Xbox app. I bought the game and had full access for a long time. Now I cannot play as every time the Error code 0xc0000420 comes up. I have tried uninstalling and re-installing and it still does not work. Any help will be greatly appreciated.

BIOS error codes

So I have motherboard with installed small LED screen, which presents BIOS error codes.

Where can I find a list of those errors. And I don't mean beep codes, but the "number" codes.

Ex after installing sound card, the motherboard startup fails with the code 15.

Example picture of code is here.

 

Windows 10 will not activate Error code 0x803F7001

Possibly there can be the problem with Microsoft activation Server, so your Windows 10 is not activated. In this scenario, you need to wait and verify if it is the issue from Microsoft’s side. But if you are getting error code 0x803f7001, you can also try these steps:

1. Open Settings app. Then go to Update and security > Activation screen > Change product.
2. Type your Windows edition product key and click Next.
3. You’ll get We couldn’t activate Windows error message.
4. Retry steps 1-3 then type your 25-characters unique product key.
5. Wait for the process to complete, Windows 10 is activated.

Hope something helps this problem
