Project generators not working on Windows

[mrmnml]

Describe the bug
On Windows 10 only the Vanilla JS project generator is working for me. All the others display a loading bar on the button for a second and then revert it back to "Proceed".

To Reproduce
Steps to reproduce the behavior:

1. Install on Windows 10
2. Create a new project
3. Fill out form
4. Select generator other than Vanilla
5. Click on Proceed

Expected behavior
Displayed generators should either work or if they fail give a hint / error message.
