  Problem 1
    - Root composer.json requires typo3/cms-core ~10.4.0 || ~11.5.0 || ~12.4.0, found typo3/cms-core[v10.4.0, ..., v10.4.37, v11.5.0, ..., v11.5.33, v12.4.0, ..., v12.4.9] but these were not loaded, likely because it conflicts with another require.
  Problem 2
    - Root composer.json requires typo3/cms-extbase ~10.4.0 || ~11.5.0 || ~12.4.0, found typo3/cms-extbase[v10.4.0, ..., v10.4.37, v11.5.0, ..., v11.5.33, v12.4.0, ..., v12.4.9] but these were not loaded, likely because it conflicts with another require.

    - typo3/cms-frontend v12.4.9 requires typo3/cms-core 12.4.9 -> found typo3/cms-core[v12.4.9] but these were not loaded, likely because it conflicts with another require.
  Problem 4
    - saschaegerer/phpstan-typo3 is locked to version 1.9.1 and an update of this package was not requested.
    - saschaegerer/phpstan-typo3 1.9.1 requires typo3/cms-core ^10.4 || ^11.5 || ^12.4 -> found typo3/cms-core[v10.4.0, ..., v10.4.37, v11.5.0, ..., v11.5.33, v12.4.0, ..., v12.4.9] but these were not loaded, likely because it conflicts with another require.
  Problem 5
    - typo3/testing-framework is locked to version 7.0.4 and an update of this package was not requested.
    - typo3/testing-framework 7.0.4 requires typo3/cms-core 11.*.*@dev || 12.*.*@dev -> found typo3/cms-core[v11.0.0, ..., v11.5.33, v12.0.0, ..., v12.4.9] but these were not loaded, likely because it conflicts with another require.
