This problem goes away when I change task queue names, so I think it may be due to an old entry in the task queue causing issues.

Sounds like you figured out the issue.
You can verify by listing open Workflows on you Temporal server and finding one that uses the default namespace and the tutorial task queue.
If you change the Worker log level to DEBUG you might find out some more information too.
We can definitely improve the error message and probably should prevent this sort of error from killing the Worker.

TBH, I don't think we can improve the error message much, looks like the Payload metadata contains non-unicode characters https://github.com/temporalio/sdk-node/blob/a25c0feca791a195eb5e50cf8c0fd9e0b5a1db83/packages/workflow/src/converter/data-converter.ts#L65
