Hello Jeff Fazio,

Problem
I understand that you are having issue to set up App Services for memory dump.
Solution
The issue you're facing it's all about authorization issues when trying to assign roles to a storage account. For more details and how to get to the bottom of the issue.
- Enable diagnostic logs for Azure AD and Azure RBAC. and let's review the logs to identify any specific errors or issues during role assignment.
- Ensure there are no resource locks preventing role assignments, and try to check if any locks exist at the subscription or resource group level.
- Try to assigning roles using both the Azure Portal and Azure CLI/PowerShell as well as using different methods can reveal underlying issues.
- Retry the role assignment after verifying the above points and monitor the Azure Activity Log for any additional error details.
