Azure Function (Service Bus Trigger) System.OperationCanceledException - azure

Question

I have an Azure Function (.net 6.0) that receives messages from Services Bus. 99% of the messages process fine but every now and then I get the System.OperationCanceledException in Application Insights.
Call Stack:
System.OperationCanceledException:

Call Stack (Just my code):
System.OperationCanceledException
Microsoft.Azure.WebJobs.ServiceBus.MessageProcessor.CompleteProcessingMessageAsync

Azure.Messaging.ServiceBus.ServiceBusProcessor+<OnProcessMessageAsync>d__104.MoveNext

Azure.Messaging.ServiceBus.ReceiverManager+<ProcessOneMessage>d__15.MoveNext
Looking at the FormattedMessage: It seems to have failed on ProcessMessageCallback. I looked it up and the only information I could find was this: Errors thrown from the user's processMessage callback passed to subscribe.
The failed method is: Azure.Messaging.ServiceBus.ServiceBusProcessor+d__104.MoveNext
To me it looks like this is a ServiceBus issue and not my code. I am using Microsoft.Azure.WebJobs.Extensions.ServiceBus v5.5.1.
Has anyone else experienced this issue or know how to resolve this?
Update:
I've added exception handling in the hopes to capture more information:
catch (OperationCanceledException ex)
{
throw new OperationCanceledException(ex.Message);
}
catch (Exception ex)
{
throw new ApplicationException(ex.Message);
}
