Hi，
Please first let me know if the issue still persists in local administrator account.
Make sure your account is under Administrator group.
This should be permission issue, please run following commands as admin to reset permission:
cd /d c:\[folders or files you would like to reset permission]
icacls * /T /Q /C /RESET
For detailed information about this command, you can refer to:
