1 year ago This issue is being tracked over in https://github.com/microsoft/pxt-microbit/issues/5100 and is being addressed in upcoming windows updates, sorry :(. You might try webusb flashing if possible and see if that works for now, or if you have another device attempt from there. Closing this issue as dup as we'll update the linked issue~
Describe the bug I find that it sometimes failed when I upload arcade hex file to microbit v2. I don't know why it failed. Error code is 521.
