Clean install : bad css

[noahfraiture]

Hello, I'm not sure if it's a bug so I want to ask here before making an issue.
It's the first time i'm using tauri and I simply followed the installation process to get tauri 2 with deno, svelte, vite and typescript.
The UI is fine on my browser, but in the openned window, the css doesn't seems to apply and this is what I see :

As you can see the image that should be there, aren't (but they are still clickable), and none of the css seem to apply

The only warning I have is the following :

▲ [WARNING] Cannot find base config file "./.svelte-kit/tsconfig.json" [tsconfig.json]

    tsconfig.json:2:13:
      2 │   "extends": "./.svelte-kit/tsconfig.json",
        ╵              ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I'm on nix so I basically installed everything needed from the documentation and added rustc that was necessary :

{
  pkgs ? import <nixpkgs> { },
}:
pkgs.mkShell {
  nativeBuildInputs = with pkgs; [
    pkg-config
    gobject-introspection
    cargo
    rustc
    cargo-tauri
    deno
  ];

  buildInputs = with pkgs; [
    at-spi2-atk
    atkmm
    cairo
    gdk-pixbuf
    glib
    gtk3
    harfbuzz
    librsvg
    libsoup_3
    pango
    webkitgtk_4_1
    openssl
  ];

  shellHook = ''
    export DIRENV="tauri"
  '';
}
