title: Installation failed, reverting ./composer.json to its original content error in Laravel 8.12
body: <p>I put this command:</p>
  <pre><code>composer require laravel/ui:^2.4
  </code></pre>
  <p>and I have the error like in the title. I found that global update of composer can help and I did that but I  have this same message. Another post said that it could remove composer.lock but it doesn't help me too. How can I solve my problem?</p>
  <p>@Edit</p>
  <p>I cant' show you all error so look at this error message</p>
