How do I change the default user that signs in on WSL?

I'm running Ubuntu terminal on windows with WSL, Every time I launch the terminal it signs me in as the root user. I've created a new user and given them root privileges so that I can code easier. How do I change the default user that gets signed in?

This is what I see when I launch:

After running su shayc I can get to my user, but how do I avoid doing thisevery time?

**UPDATE: **I've tried setting a default user in /etc/wsl.conf

Note: also I am not able to run WSL commands
