I have had similar problems with parttool.py, but they turned out to be hardware problems. That command certainly works for me on latest sdk but I'm using linux.
Basically all parttool.py is doing is calling esp_tool.py so just find out that command and run it directly and you will get better errors. You can see from the error it's calling esp_tool read_flash something something, it's probably trying to get the address of the partition you've specified.
If you know your partition table then you can just call esp_tool write_flash directly.
