Installed fresh installation of Windows 10 Pro x64 1903, along with dependencies required in contributing document (NSIS 2.51, Python2.7, VS with Desktop C++ env, jq, msys-make etc.)
Cloned the repository recursively with scripts submodule.
Ran pip install -r requirements.txt
Ran make electron-develop Had some issues here, some dependencies required mingw32-make, for some reason things like shasum and sha1sum were missing, managed to fix that.
Finally managed to install all dependencies and ran make webpack
After everything, ran make electron-build and used the output setup to install Etcher on my PC.
Tried to flash an image, got thrown the error above.

And yes, I’m running etcher as a built package.
