Error on JupyterLab and SageMaker Console

On the Sagemaker console I get the error:


User: arn:aws:sts::151122591112:assumed-role/voclabs/user1793341=Marianne_Mullan is not authorized to perform: sagemaker:ListHyperParameterTuningJobs with an explicit deny in an identity-based policy

On the Jupyter Notebook I get:
File Save Error for C1_W3_Assignment.ipynb
Auth token containing insufficient permissions

Both were working before.

I have not reached the 4 hour course limit but this is preventing my from finishing the notebook. Any help would be appreciated. Many thanks
