Hey Emily, Could you take a look at this? It seems to be crashing on something related to moving artifacts around

I kicked off a bisect since there seems to be a regression range where this started failing.  

The odd thing here is that the test passes but this fails on cleanup on the bot?  The uploading itself to cloud storage didn't fail.  Ned can you comment on when this failure happens in telemetry?

@Emily, can you show me how you kicked off that bisect? I wasn't sure how to do it given that the test passes but has that bot failure
thanks!

📍 Couldn't reproduce a difference.
