@devlie thank you for the report!

Could I ask you to download https://github.com/git-for-windows/msys2-runtime/suites/12984391642/artifacts/702653381 (the PR build artifact of git-for-windows/msys2-runtime#52), and unpack usr\bin\msys-2.0.dll over the existing one in your Git for Windows setup, then verify that this fixes it?

@dscho works like a charm! Thanks for the workaround :)
