I am trying to delete Cluster Role from Windows 2012 Failover Cluster but get above error in both WFC Manager GUI and PS. AG1 cluster role is still visible in GUI and Cluster Core Resources is empty in GUI.
Please advise how AG1 role can be removed and cluster core resources be visible again.
As a quick workaround ended up deleting whole cluster:
And then recreating a new one.
