- illuminate/support[v8.0.0, ..., v8.11.2] require php ^7.3 -> your php version (8.0.15) does not satisfy that requirement.
- Root composer.json requires cartalyst/sentinel ^5.1 -> satisfiable by cartalyst/sentinel[v5.1.0, 5.x-dev].
Sentinel 6 for Laravel 9 is on the master branch, make sure your minimum stability is set to dev, you can then install it using "cartalyst/sentinel": "^6.0"
