03/14/2023, 10:57 PMThis seems to happen relatively consistently but I managed to flash one of my boards

03/14/2023, 11:14 PMSuper interesting... I'll see if there's some issue with esptool, my system, and these boards

03/14/2023, 11:14 PMWe just bundle it up with the pyinstaller

We will continue listening to feedback. Maybe we are using a version that is older, or the windows executable isn't working right.
If more users run into it we will investigate a bit further.
Unfortunately none of us use Windows, so we aren't always seeing Windows issues early.

03/15/2023, 5:36 AMCould you check which usb-serial converter chip the failing board uses?

03/15/2023, 5:37 AMAccording to https://github.com/espressif/esptool/issues/280 it could be a driver issue.

03/15/2023, 5:38 AMEspecially for CHxxx chips.
