Problem when installing on Laravel 8.79

[nietjoost]

`` Problem 1
- Root composer.json requires spatie/laravel-fractal ^6.0 -> satisfiable by spatie/laravel-fractal[6.0.0].
- spatie/laravel-fractal 6.0.0 requires illuminate/contracts ^9.0 -> found illuminate/contracts[dev-master, v9.0.0-beta.1, 9.x-dev (alias of dev-master)] but these were not loaded, likely because it conflicts with another require.

Is there anyone who knows how to fix this isue?
