Error building on windows 10

[gatlinnewhouse]

• I am running an official build of TWRP, downloaded from https://twrp.me/Devices/
• I am running the latest version of TWRP
• I have read the FAQ (https://twrp.me/FAQ/)
• I have searched for my issue and it does not already exist

Trying to build TWRP for my device and I cannot mka recovery image due to an error with rsync chgrp. I think this is due to me trying to build it using Windows Subsystem for Linux on an NTFS partition (but maybe I am wrong).

Here's the error message:

If you need more information let me know.

Sorry. We don't support wsl officially.

I know this isn't officially supported, but I currently build TWRP for all of my maintained devices without an issue in WSL. Just make sure you're using WSL 2. If you're not, that's probably why you're having issues.

Thanks @CaptainThrowback, going to try that since I know I am running WSL 1.

Still getting the error on WSL 2.
