Upgrading Drupal

On upgrading from 10.1.8 to 10.3.2, I have an error about the module, media_library_theme_reset.

I read the information below.

I just have upgraded Drupal Core from 10.1 to 10.3.2, and now have some warnings.

 Deprecated modules installed  Deprecated modules found: Layout Builder Expose All Field Blocks

The module was not installed before upgrading core, and after upgrading, this module is listed in Core Module and checked with grayed-out mark, so I cant't uncheck this module. 

How can I solve this warning?

Thanks.

Trying to upgrade my 10.3.1 test environment to 11.0.0 now that it's out. I'm copying commands from the 11.0.0 upgrade page.

The first, 'composer update "drupal/core-*" --with-all-dependencies' results in 'Nothing to install, update or remove'.

The second 'composer require drupal/core-recommended:11.0.0 drupal/core-composer-scaffold:11.0.0 drupal/core-project-message:11.0.0 drupal/core-vendor-hardening:11.0.0 --update-with-all-dependencies' results in this:
