Thanks @Oddant1!
Generally speaking, sudo should be considered a dangerous command to leverage, and usually isn't going to solve the root of the problem (see what I did there?). In this case, please take a closer look at your file permissions - it is possible that things are set up in a way that your WSL user account doesn't have the necessary permissions.
Since QIIME 2 just honors whatever the file permissions are, the "right" way to solve this at the filesystem level - there isn't anything you can do in QIIME 2 to circumvent those permission.
Keep us posted, @mkk!
