I can't remove a policy in Azure.

Error is:
Could not delete 'Policy Assignment' from 'Azure for

Students'.

The client 'asdf@asdf' with object id

'ae17a624-72de-4644-9afd-4ba6e79aa915' has

permission to perform action

'Microsoft.Authorization/policyAssignments/delete' on

scope '/subscriptions/c46383de-fbd6-4950-b598-

99cf6ed0764a/providers/Microsoft.Authorization/polic ...

491a-4f3c-8d99-ad3ec79a0486'; however, the access is

denied because of the deny assignment with name

f057b07c-491a-4f3c-8d99-ad3ec79a0486' and Id
