Can you confirm that https://www.swift.org/install/windows/ is the documentation you refer to?

This will be built from Apple's Swift fork, I think @charles-zablit would be able find out it's specific to that version.

This looks like the same crash as swiftlang#11779.

The TL;DR to fix it is to install Python 3.10 and make sure it's in your PATH.
