Look for the tab that pertains to the error you are seeing.

It has possible solutions with steps for you to follow to try to solve the problem.

If you can't do it at all, the last step is to request maintenance,

If your console is under warranty:

There is only one way to contact the warranty and request the opening of an OS (service order) for warranted products.

Click on the "Enter" option, it will take you to your registered devices page, select your xbox and there will be repair options, just follow the steps from there.

Same issue. Was using dev mode without any issues an hour ago, then updated to the latest OS and now I’m getting blocked with this same message when I try switching to dev mode...

No not the insider Programm i think I use the officail dev mode app to switch my xbox to dev mode from retail

I don't remember precisely what happened before this started, but I do recall switching to Developer Mode at one point before the Microsoft Store stopped working with this same error code. I just tried restarting in Dev Mode again, then switching back,
but no joy (same issue).
