Does microsoft still do xbox one fixes in 2023?

No. They no longer repair Xbox One consoles.

nothing to do with Microsoft, this is on Activision to fix, Microsoft won't own Activision until at least June 2023 or longer if there are court cases.

If you had paid Microsoft to fix it originally, it would probably no longer be an issue. I believe they no longer repair any consoles from 2009 and earlier, but since you've had yours repaired by someone else, they wouldn't touch it. Self repair or repair
by anyone who is not Microsoft is a violation of the terms of service. In your case, it would be best to just get a new one.

I was afraid of this answer. If I was looking for a free fix, that would be entirely reasonable to refuse to service it, but I only went that way because Microsoft told me that were not sure if that was fixable.

not that i am aware, they don't even repair the black xbox one anymore.
