Class "Drupal\layout_builder_browser\Controller\LibraryController" not found

It is not the wrong name.

I think the patch https://git.drupalcode.org/project/sobki_profile_dsfr/-/blob/10.0.x/comp... has not been applied properly.

You are right. My root composer.json was missing "enable-patching": true and the package "cweagans/composer-patches".

After installing it and configuring all this, all the patches are now applied. Thanks!
