Not all problems relate to this module. (I just left them there because ideally they would be solved in all modules... I will create cases there as well)
composer require 'drupal/diff:^2.0@beta'
Your requirements could not be resolved to an installable set of packages.
Problem 1
- Root composer.json requires drupal/diff ^2.0@beta, found drupal/diff[2.0.0-beta1, 2.0.0-beta2] but these were not loaded, likely because it conflicts with another require.
Problem 2
- drupal/elogger is locked to version 1.1.13 and an update of this package was not requested.
- drupal/elogger 1.1.13 requires drupal/diff >=1.0 -> found drupal/diff[1.0.0-beta1, ..., 1.7.0, 2.0.0-beta1, 2.0.0-beta2] but these were not loaded, likely because it conflicts with another require.
Problem 3
- drupal/entity_diff_ui is locked to version 2.0.0-alpha1 and an update of this package was not requested.
- drupal/entity_diff_ui 2.0.0-alpha1 requires drupal/diff ^1.1 -> found drupal/diff[1.1.0, ..., 1.7.0] but it conflicts with your root composer.json require (^2.0@beta).
Problem 4
- drupal/diff_plus dev-1.0.x requires drupal/diff ^1.0 -> found drupal/diff[1.0.0-beta1, ..., 1.7.0] but it conflicts with your root composer.json require (^2.0@beta).
- drupal/diff_plus 1.0.x-dev is an alias of drupal/diff_plus dev-1.0.x and thus requires it to be installed too.
- Root composer.json requires drupal/diff_plus 1.0.x-dev@dev -> satisfiable by drupal/diff_plus[1.0.x-dev (alias of dev-1.0.x)].
