Getting uninitialized constant Spree::Admin::UserSessionsController when trying to access admin in fresh install

Question

I've done a fresh install of ruby on rails and solidus with WSL using ubuntu.

I can access the frontend store just fine, see the default products and such, but when I try to access the admin page using http://127.0.0.1:3000/admin/login I get the following error:

I tried searching for it but got nowhere, these are some specs of my system:

ruby -v ruby 3.2.2 (2023-03-30 revision e51014f9c0) [x86_64-linux]

rails -v Rails 7.0.5

I've trying searching for the same error online but got no clear answer, i'm expecting that the admin page begins working.

EDIT:

So the steps I did to install solidus is exactly what it is described in their github, nothing more, nothing less

I ran these commands in sequence:

rails new my_store

bundle add solidus

bin/rails g solidus:install

bin/rails s

I can access the frontend of the store just fine using localhost, but when I try to access /admin is when I encounter the error, Ive tried using windows, and then WSL with ubuntu, got same error on both.

dont have another machine to test it rn.

here's a copy of the error as plain text:
