Updating dependencies
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Root composer.json requires typo3/cms-core ^13.4 || ^14.0, found typo3/cms-core[v13.4.0, ..., v13.4.24, v14.0.0, v14.0.1, v14.0.2, v14.1.0] but these were not loaded, likely because it conflicts with another require.
  Problem 2
    - Root composer.json requires typo3/cms-backend ^13.4 || ^14.0 -> satisfiable by typo3/cms-backend[v14.1.0].
    - typo3/cms-backend v14.1.0 requires typo3/cms-core 14.1.0 -> found typo3/cms-core[v14.1.0] but these were not loaded, likely because it conflicts with another require.
  Problem 3
    - saschaegerer/phpstan-typo3 is locked to version 2.1.1 and an update of this package was not requested.
    - saschaegerer/phpstan-typo3 2.1.1 requires typo3/cms-core ^13.4.3 -> found typo3/cms-core[v13.4.3, ..., v13.4.24] but it conflicts with your temporary update constraint (typo3/cms-core:14.1.0).
  Problem 4
    - Root composer.json requires typo3/cms-filelist ^13.4 || ^14.0 -> satisfiable by typo3/cms-filelist[v14.1.0].
    - typo3/cms-filelist v14.1.0 requires typo3/cms-core 14.1.0 -> found typo3/cms-core[v14.1.0] but these were not loaded, likely because it conflicts with another require.
