Nix-shell crashing randomly

Hey everyone, I’m trying to install holochain on WSL2 in Windows 10 and I only get to the nix-shell command step of this developers/requirements/setup/ in the holochain gym and it doesn’t seem to build correctly, I get this:

or something like this, it seems to change every time:

gyazo / f75b9d25625de05e5cdca23ad07ad25b

Does something not line up here?
PS C:\Users\super> wsl --list -v
NAME STATE VERSION

  • Ubuntu-18.04 Running 2

I would really appreciate any help in getting this set up. Thank you all!
