since today I have the following error when I tried to create an ad-hoc IPA

I've already downloaded the new AppleWWDRCA.cer and the G2, then I rebooted the mac, clean the project, clean the project folder, deleted the related certificates/profile and reinstall them but the error persist.
And I think is related but all my certificate in the keychain display (null) when I tried to export, copy, etc
and Here you can see all my apple related certificate + Apple Application Integration Certification Authority not present but valid until 26/08/2017 :
