Microsoft Defender - error 0x800704ec

Question

Hello,

We are in the process of deploying Microsoft Defender for our entire computer population.

We are testing on our machine.

Before we were using ESET that we deploy via the enterprise portal (Intune).
Required assignment rule to "Included
We have changed the "Required" rule of the group to "Included".

• added the group in "Uninstall".

We have added the Microsoft Defender app to the enterprise portal.

ESET is now uninstalled.
Microsoft Defender is well installed.

However when I launch Microsoft Defender and click on "Connect" I get this error:

this program is blocked by a group policy 0x800704ec

Any idea where the problem could come from, I tried on another machine and it's the same.

Thanks
