Problem 1
- symfony/yaml[v4.0.10, ..., v4.4.8] require php ^7.1.3 -> your php version (8.2.16.0) does not satisfy that requirement.
- symfony/yaml[v5.0.0, ..., v5.0.8] require php ^7.2.5 -> your php version (8.2.16.0) does not satisfy that requirement.
- contao/tcpdf-bundle[1.2.2, ..., 1.2.3] require symfony/yaml 3.4.* || ^4.1 || ^5.0 -> satisfiable by symfony/yaml[v3.4.0, ..., v3.4.47, v4.1.0, ..., v4.4.45, v5.0.0, ..., v5.4.35].

- You can only install one version of a package, so only one of these can be installed: symfony/yaml[2.0.4, ..., v2.8.52, v3.0.0, ..., v3.4.47, v4.0.0, ..., v4.4.45, v5.0.0, ..., v5.4.35, v6.0.0, ..., v6.4.3, v7.0.0, v7.0.3].

- contao/tcpdf-bundle 1.2.0 requires php ^7.1 -> your php version (8.2.16.0) does not satisfy that requirement.
- Root composer.json requires contao/calendar-bundle 5.3.* -> satisfiable by contao/calendar-bundle[5.3.0].
- Root composer.json requires contao/tcpdf-bundle ^1.2 -> satisfiable by contao/tcpdf-bundle[1.2.0, 1.2.1, 1.2.2, 1.2.3].
