What exactly happened when you clicked/tapped on Computer Management?
Did you receive an error message?
Please post the sfc /scannow log for the scan you ran.
To find sfc /scannow log click/tap on File Explorer, select the drive which Windows is installed on (this usually is the C: drive), click/tap on Windows, then Logs, then CBS. If there are more than one log you can identify the log you want by the date and time it was run.
Copy and paste the log at the host website I've suggested below.
This log usually is very large, for this reason you should use a host website like Dropbox to post the log. You can start a free 30 day trial. Once you have loaded the log at Dropbox post a link to the website.
Did the sfc /scannow find any file corruption?
Did you run the DISM scan after running the sfc /scannow?
