Windows 10: Sign out problem from Windows 11 pro 22H2

I signed in using a personal email by mistake on a work computer to sign into Microsoft Office so I could use Word, Excel, etc, and now I cannot sign out. I can see my account under "Email & Accounts" in the Windows 11 pro settings menu, and there's seemingly no way to remove it. I even clicked manage, got redirected to some stupid page in my browser that was equally as unhelpful, instead of being able to control it from the computer.I don't want my account on this computer. I don't want my Office subscription linked to it. I don't want my OneDrive linked to it. I want everything about m

Cannot update Windows 11 to build 22h2

Need more help than support web site offers. I would like to update a Windows Pro 21h2 to 22h2.

I've tried every suggestion at Troubleshoot problems updating Windows - Microsoft Support short of "Perfrom a clean installation of Windows 11." That list is comprehensive and includes everything I would have thought of on my own and then some. None of the troubleshooting suggestions solved the problem. The system in question is a Lenovo ThinkCentre M90n desktop running Windows 11 Pro Version 21H2.

In addition to all the steps at the above link, I've also tried installing by using Windows 11 Installation Assistant. Installation Assistant downloads and goes through the long installation process. But then very shortly after the reboot starts, it says, "Undoing changes" and boots back into the old build.
