Uncaught Error: Class "Illuminate\Foundation\Application" not found

[Farids87]

Hi,

I'm really stucked to generate key on PHP as I'm always having some issues despite all my tests...

When I run this command below:

php artisan key:generate

I'm getting this:

PHP Fatal error: Uncaught Error: Class "Illuminate\Foundation\Application" not found in C:\Users\sissa\Documents\project-main\bootstrap\app.php:14
Stack trace:
#0 C:\Users\sissa\Documents\project-main\artisan(20): require_once()
#1 {main}
thrown in C:\Users\sissa\Documents\project-main\bootstrap\app.php on line 14

Here is the line 14 from bootstrap\app.php:

$app = new Illuminate\Foundation\Application(
    $_ENV['APP_BASE_PATH'] ?? dirname(__DIR__)
);

Before this I ran the command composer dump-autoload because vendor folder was not present on project directory.
I also removed composer lock file.

I tried to run command below:
composer install --no-scripts

With result below:
No composer.lock file present. Updating dependencies to latest instead
of installing from lock file. See https://getcomposer.org/install for more information.

Your requirements could not be resolved to an installable set of packages.

Problem 1
- league/flysystem-aws-s3-v3[3.0.0, ..., 3.16.0] require league/mime-type-detection ^1.0.0 -> satisfiable by league/mime-type-detection[1.0.0, ..., 1.13.0].
- league/mime-type-detection[1.0.0, ..., 1.3.0] require php ^7.2 -> your php version (8.2.10) does not satisfy that requirement.
- league/mime-type-detection[1.4.0, ..., 1.13.0] require ext-fileinfo * -> it is missing from your system. Install or enable PHP's fileinfo extension.
- Root composer.json requires league/flysystem-aws-s3-v3 ^3.0 -> satisfiable by league/flysystem-aws-s3-v3[3.0.0, ..., 3.16.0].

To enable extensions, verify that they are enabled in your .ini files:
- C:\tools\php82\php.ini
You can also run php --ini in a terminal to see which files are used
by PHP in CLI mode.
Alternatively, you can run Composer with --ignore-platform-req=ext-fileinfo to temporarily ignore these required extensions.

Any suggestions?

Thanks in advance
