Problem 1
- spatie/crawler[4.7.6, ..., v4.x-dev] require guzzlehttp/psr7 ^1.4 -> found guzzlehttp/psr7[1.4.0, ..., 1.x-dev] but the package is fixed to 2.1.0 (lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command.
- spatie/crawler[4.7.0, ..., 4.7.5] require php ^7.1 -> your php version (8.0.10) does not satisfy that requirement.
- spatie/laravel-export 0.3.9 requires spatie/crawler ^4.7 -> satisfiable by spatie/crawler[4.7.0, ..., v4.x-dev].
- Root composer.json requires spatie/laravel-export ^0.3.9 -> satisfiable by spatie/laravel-export[0.3.9].

Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.

Installation failed, reverting ./composer.json and ./composer.lock to their original content.
