This might be an issue with trying to run under /mnt when using WSL. Try again after installing Algo somewhere other than /mnt.

[ThunderMerweS]

I think Windows is broken :)

Just did the whole thing on a spare Raspberry Pi with not a single hiccup.

Thanks for the response though, appreciate it.

It's a known WSL and /mnt/ issue. microsoft/WSL#81
