For Composer usage support provide the composer.json file.

Hi @yuvalbh,
I tried to recreate this issue by following your steps, but could not replicate it.

Steps followed to reproduce

• made a fresh drupal 10.3.1 site installation. Attached the screen shot for the system info.
• Updated to drupal version 10.4.0, following from Drupal update document → applied this command to update the
  

  composer require drupal/core-recommended:10.4.0 drupal/core-composer-scaffold:10.4.0 drupal/core-project-message:10.4.0 
  --update-with-all-dependencies

  then drush updb followed by drush cr. Attaching a screen shot for the system info.

Please provide more info to reproduce the issue.

You could try checking for any existing conflicts in composer.json

composer why guzzlehttp/guzzle

If a specific package is requiring an incompatible version of Guzzle, update it to a version that is compatible with guzzlehttp/guzzle ~7.9.2 or you could Temporarily remove conflicting dependencies then proceed with the Drupal upgrade.

If there are no conflicting packages

composer require guzzlehttp/guzzle:~7.9.2 --update-with-all-dependencies

Then retry the upgrade command for Drupal core.

We need more information to be able to reproduce this.

issue solved:
The old aws/aws-sdk-php was set to be with guzzlehttp/guzzle version 7.8.2, after updating aws issue solved.

command:
composer require aws/aws-sdk-php --update-with-all-dependencies

in order to reproduce issue you need to have: aws/aws-sdk-php v3.316.9
updating aws/aws-sdk-php (3.316.9 => 3.336.13)

check your aws/aws-sdk-php with command: composer show aws/aws-sdk-php
