AWS Glue "Task allocated capacity exceeded limit" solved but error persist at notebook session creation

Yesterday we had the error Failed to start notebook server "Task allocated capacity exceeded limit. (Service: AWSGlueJobExecutor; Status Code: 400; Error Code: InvalidInputException)" caused by Max task dpus per account quota defined as 0 internally by AWS. Once it was fixed by returning it to its default value following documentation, ETLs are able to run but the error persist at notebook session creation:

Exception encountered while creating session: An error occurred (ResourceNumberLimitExceededException) when calling the CreateSession operation: Failed to meet resource limits for operation

botocore.errorfactory.ResourceNumberLimitExceededException: An error occurred (ResourceNumberLimitExceededException) when calling the CreateSession operation: Failed to meet resource limits for operation

Increasing the limits of Max concurrent job runs per account and Max task dpus per account has not solved the error
