laravel debugbar package installation failed

I am trying to install the Debugbar Laravel package to my website using this command:

composer require barryvdh/laravel-debugbar --dev

But it shows error on the terminal

Installation failed, reverting ./composer.json and ./composer.lock to
their original content.
 
[ErrorException]   file_get_contents(): Filename cannot be empty

I have searched a lot but cannot find the proper solution, I have also tried other testing packages like a telescope, clockwork but nothing works and installs.

My composer.json file:

Laravel framework: 5.5

PHP installed on my system: 7.4

I have even removed kylekatarnls folder from the vendors folder and tried again but still, nothing works.
