I created an Angular project using the CLI. I'm using SCSS, and I included Angular Material with a custom theme iirc. I added a couple dummy components, and the app still built fine. Then I needed to style my components using Angular Material. In order to do so, I added @use '~@angular/material' as mat; to the first line of my style.scss file. Once I did this, the app will no longer build. It always throws the following error:
ERROR in ./src/styles.scss (./node_modules/css-loader/dist/cjs.js??ref--13-1!./node_modules/postcss-loader/src??embedded!./node_modules/resolve-url-loader??ref--13-3!./node_modules/sass-loader/dist/cjs.js??ref--13-4!./src/styles.scss)
Module build failed (from ./node_modules/sass-loader/dist/cjs.js):
SassError: Can't find stylesheet to import.
╷

│ ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
╵

I have no idea what I'm doing wrong; I was under the impression that importing Angular Material this way would just work. Am I doing something wrong?
Here is my entire style.scss file if that's helpful:
@use '~@angular/material' as mat;
// Custom Theming for Angular Material
// For more information: https://material.angular.io/guide/theming
@import '~@angular/material/theming';
// Plus imports for other components in your app.
// Include the common styles for Angular Material. We include this here so that you only
// have to load a single css file for Angular Material in your app.
// Be sure that you only ever include this mixin once!
@include mat-core();
// For each palette, you can optionally specify a default, lighter, and darker hue.
$aphrodite-primary: mat-palette($mat-indigo);
$aphrodite-accent: mat-palette($mat-pink, A200, A100, A400);
// The warn palette is optional (defaults to red).
$aphrodite-warn: mat-palette($mat-red);
// Create the theme object. A theme consists of configurations for individual
// theming systems such as "color" or "typography".
$aphrodite-theme: mat-light-theme((
color: (
primary: $aphrodite-primary,
accent: $aphrodite-accent,
warn: $aphrodite-warn,
)
));
// Include theme styles for core and each component used in your app.
// Alternatively, you can import and @include the theme mixins for each component
// that you are using.
@include angular-material-theme($aphrodite-theme);
/* You can add global styles to this file, and also import other style files */
@import '~normalize.css';
@import 'sassVars.scss';
