according to sass/sass#3300, it works fine when add sourceMapUrl in load function return. Not sure it's a bug...

const contents = await new Promise((resolve, reject) => {
  // Old version of `enhanced-resolve` supports only path as a string
  // TODO simplify in the next major release and pass URL
  const canonicalPath = _url.default.fileURLToPath(canonicalUrl);
  loaderContext.fs.readFile(canonicalPath, "utf8", (err, content) => {
    if (err) {
      reject(err);
      return;
    }
    resolve(content);
  });
});
return {
  contents,
  syntax,
+  sourceMapUrl: canonicalUrl,
};

Sorry not related to sass-loader please open an issue in resolve-url-loader, we always return absolute urls, maybe you have source maps comment in your CSS libraries

If you provide reproducible test repo I can show you there is a bug
