Settings options not being available like that sounds like a system file may have become corrupted, it happens (often following a Windows Update).
The first, simplest, thing to try is a Restart of your laptop, that's a "Restart" and not a Shutdown/Boot.
Then try to access the sign-in settings options again.
If it's still not working then there are a couple of commands that can check and restore the system image.
Firstly it's usually a good idea to make sure that the stored system image is 'healthy'.
(Some people skip this because it takes extra time, but if a job's worth doing ....)
-
Open the Start menu and begin typing the word command
-
In the window that opens select 'Command Prompt', and select the 'Run as administrator' option.
An 'elevated' (administrator) command window will open.
</li>
<li>
Type, or copy/paste, <strong>DISM /Online /Cleanup-Image /RestoreHealth</strong> and press Enter.
</li>
That will check the stored system image and repair any errors that are found in it.
Note that it may appear to be stuck after writing a couple of lines, this is normal behavior. After a minute you should see some stars and a percentage counter as the process continues, it will say when it has completed sucessfully.
Next run the System File Checker:
(This can be run without doing the DISM first).
-
If you don't already have an elevated command window open after doing a DISM then follow steps 1 & 2 above.
-
Type, or copy/paste, SFC /scannow
That checks your system files against the stored image, and repairs them if necessary.
If errors are found and fixed then run the same SFC /scannow command again, when there are errors it can sometimes take 3 or 4 runs to fix them all.
Restart your computer and check if the sign-in settings problem has now been fixed.
Here's a screenshot of the DISM and SFC process that I just ran on this laptop.
You can see that SFC found and repaired errors, so I ran the "SFC /scannow" command a second time which then reported OK.
(TBH I haven't been noticing any problems with this laptop so I'm glad I checked - some people do a check once a week or once a month).
