Windows Defender error : 0x80070005



I am deploying Windows Defender via Group Policy.
Once the user logs into the PC after the intall, Windows Defender
automatically updates itself and runs a scan,but the error message
'Application failed to initialize : 0x80070005. Access is denied' appears
I have installed Windows Defender manually on other test PCs and have
experienced no issues.
This error message continues to popup until I reboot the PC again.

Any ideas on how to resolve this issue?
