Installing 4.0.0-beta1 via composer downgrades CiviCRM to 5.67.1

I think its possible that something else is causing a downgrade. CiviCRM Entity itself is not making any version requirements for CiviCRM
https://github.com/eileenmcnaughton/civicrm_entity/blob/4.0.x/composer.json

{
    "name": "drupal/civicrm_entity",
    "type": "drupal-module",
    "description": "Expose CiviCRM entities as Drupal entities.",
    "homepage": "http://drupal.org/project/civicrm_entity",
    "license": "GPL-2.0+",
    "require": {
        "drupal/core": "^10",
        "civicrm/civicrm-drupal-8": "*"
    },
    "require-dev": {
        "drupal/fullcalendar_view": "^5.0"
    },
    "minimum-stability": "dev"
}

I'll look into it, but can't think of why it would downgrade from 5.67.3 to 5.67.1

I tested upgrading a site from 5.63 to 5.67.3 and then upgrading CiviCRM, and also requiring into a blank D10 site
composer create-project drupal/recommended-project new-blank-d10
composer require civicrm/civicrm-core civicrm/civicrm-packages civicrm/civicrm-drupal-8
as of this date, 5.67.3 pulled in for CiviCRM, then
composer require 'drupal/civicrm_entity:^4.0@beta'

Composer kept civicrm at 5.67.3 afterwards.

I'll need more specific information to assist

Yeah this appears to be an incorrect report. Thanks for looking into this.
