Error Code (0x8007012b

That's really odd.
Corbin may I know if you have installed the game on a external hard drive / partition?

If that's the case please install the game in the C: drive.

----

If that doesn't work, please try this:

Reinstall Gaming Services using powershell command

Press Windows key + X and then select Windows PowerShell (Admin).

Type or copy / past the following command and press Enter:

Get-AppxPackage *gamingservices* -allusers | remove-appxpackage -allusers

Restart the PC and Open the Xbox application.

A blue notification with the following message is going to appear at the bottom:
"This app needs an extra component. Gaming Services is needed for playing some games. Administrator approval required. Install"

Select Install to reinstall Gaming Services, once installed check again

Could you try repairing and resetting Minecraft dungeons one more time?

Or if the issue persists, reinstall the game

I believe additional information is needed.

Where are you experiencing this issue. On PC or Xbox?
If it's on PC, are you on Windows 10 or 11?
If it's on Xbox which one do you have?

Is this happening only with Minecraft dungeons?

And, which troubleshooting steps you have done so far to fix this problem. In that way I can advise you different things or how to proceed

Windows 11 And Only Minecraft dungeons

well now it broke again

if you wonder what its doing i open up the app then it pops up with a error screen

then i close it and the app closes
