plz help
Your user account is corrupt.
Your posted diagram proves it.
You can further demonstrate that fact by trying to run anything as an Admin, even a cmd/powershell/terminal window. You will get the same diagram with its
Yes button missing / greyed out.
If you have another user account that is an Admin, log into it now and,
as your very first action, create an*** additional local Admin account so you can then pause to take a breath & post back about your success.
- I think this is the case judging by your latest update but, just in case I misunderstood your updated post, I've also described what to do otherwise.
1 If you do not already have another Admin user account then you will have to work through this procedure.

It was written for Windows 10 so you'll see some differences as you go through but it should get you through alright.
OR
2 If you have a recent system image from before the problem appeared then you might prefer to restore that image instead.
- You'll first need to backup those files that have changed since the image was made [in C:\Users\Documents & other places].
- Your first action upon successful restoration should be to make at least one*** spare, local, password-protected Admin account so that you are prepared for any future account corruption.

As you'll see in that tutorial, I always have two spare, local, password-protected Admin accounts.
All the best of luck,
