Azure disk pvc's no longer working after upgrading to 2.6.8

I Upgraded my RKE cluster to version 1.24.3 and my rancher enviroment running on it to version 2.6.8 and after that i noticed that pvc’s won’t attach anymore

in the logs of the kube-controller-manager i find this hint

I0920 10:32:50.590931 1 event.go:294] “Event occurred” object=“default/z” fieldPath=“” kind=“PersistentVolumeClaim” apiVersion=“v1” type=“Normal” reason=“ExternalProvisioning” message=“waiting for a volume to be created, either by external provisioner "" or manually created by system administrator”

I haven’t changed anything to the app registration, the secret hasn’t expired nor have the permissions for the app registration changed.

Is there anyone else that is running in to this issue.
