Installation failed, reverting ./composer.json to its original content.

I already tried installing an older version as suggested by this post: Installing laravel dusk on 5.5.34

Other commands I’ve tried

composer require --dev laravel/dusk:^2.0
composer require --dev laravel/dusk:"^2.0" 
composer require --dev laravel/dusk:^4.0  
composer require --dev laravel/dusk:"^4.0" 
composer require --dev laravel/dusk:5.0

All of them give me the same error. So how do I get Dusk installed into my project?
