Big Sur Mail program crash with SpeedTracer Error

I get this error at launch of Main in Big Sur:

NSURLConnection to https://speedtracer.apple.com/tracer/analyze failed with error: A server with the specified hostname could not be found.

Any workaround?

Workaround for me was moving the ~/Library/Mail folder out to the Desktop and letting Mail remake the folder. Be aware, I'm not sure how destructive this is to attachments, settings and mbox contents, but it has let me load Mail to poke around for now and all Mail is being shown and searched with the same layout I had used previously.
I've also seen this same issue shown as the issue for crashing in Safari, as well as the new Xcode beta so I don't think it's purely isolated to Mail.app unfortunately.
i am constantly seeing this with pretty much any built-in app in Big Sur beta1 and 2. its impossible to launch TextEdit, crashes with this message any time
