mono.security.dll is denied?

When I try to build my apk this message appears

UnauthorizedAccessException: Access to the path “C:\Users\Diyar\Documents\plane game\Temp\StagingArea\assets\bin\Data\Managed\Mono.Security.dll” is denied.

I searched the web and I couldn’t find any answer, I tried to run it As Administrator but it shows the same problem.

any help well be appreciated

Access is denied so start unity in Administrator mode or root access, whatever your OS calls it.
