Windows 10: Illegal State Change Requested?

I've been trying to sign in to my Microsoft account so I could update my computer to Windows 11 for what's felt like a year. I recently tried signing in to recover some information but got an "Illegal State Change Requested" notification when I did. I never requested any change or such. The best I can remember is trying to delete my account a few years ago but decided not to. I need this fixed ASAP.

Illegal state change request???

When I tried to sign in I was told, We are unable to sign you in. An illegal state change was requested? What does that mean? I did not ask for any change!

 

Illegal State was requested

I basically have the same question as here. I have reset the password. Added information to my Microsoft account. I receive the "Illegal State was requested" when verifying my account in "your info".

Redirecting

I'll also point out there are a number of people asking this. This issue is preventing me from changing the email on my computer to the more current one.

 

An illegal state change was requested

I was trying to install Your Phone app and set it up, but was stuck at 60% progress. After some time trying to make it work, I ended up in Settings>My Account, and under Your Info it said "You need to update some info for your Microsoft account. When I click
to "Update info", it prompts me to enter my password, then a small window appears just like an error message, saying "An illegal state change was requested".

What is this ? And how can I solve this issue ??

Any help will be appreciated, Thank you !
