Logging not working properly

Hi, I have a problem with logging in Laravel. I'm using Laravel 10 with Jetstream (Laravel v10.45.1 (PHP v8.3.3) to be precise)

Now my problem is, that none of my tries to log into logfiles via Log:: works.

For example: I have a Usercontroller, where I update the users roles (via spatie) and want to log that event.

public function update(Request $request)
    {
        $validatedData = $request->validate([
            'user_id' => 'required|exists:users,id',
            'roles' => 'array',
        ]);

        $user = User::findOrFail($request->user_id);

        $user->roles()->sync($request->input('roles', []));
        Log::info('Edited Info for user {givenName} {sn}', ['givenName' => $user->givenName, 'sn' => $user->sn]);

        return redirect()->back()->with('success', 'User successfully updated');
    }

now this Log-Message never gets created in the logfiles, but laravel isn't throwing an error, so I guess the syntax is correct. The weird part is, that errors generated from the console get logged. For example if I try to call php artisan pail while not having pail installed I get the error message written to the logfiles.

Below my logging.php (excerpts):

'default' => env('LOG_CHANNEL', 'stack'),

'channels' => [
        'stack' => [
            'driver' => 'stack',
            'channels' => ['single', 'daily'],
            'ignore_exceptions' => false,
        ],

        'single' => [
            'driver' => 'single',
            'path' => env('LOG_SINGLE_PATH', 'storage/logs/laravel.log'),
            'level' => env('LOG_LEVEL', 'debug'),
            'permissions' => 0775,
            'replace_placeholders' => true,
        ],

        'daily' => [
            'driver' => 'daily',
            'path' => env('LOG_DAILY_PATH', 'storage/logs/laravel.log'),
            'level' => env('LOG_LEVEL', 'debug'),
            'permissions' => 0775,
            'days' => 14,
            'replace_placeholders' => true,
        ],

		[...]

        'emergency' => [
            'path' => env('LOG_EMERGENCY_PATH', 'storage/logs/laravel.log'),
        ],
    ],

and corresponding .env parts:

LOG_CHANNEL=stack
LOG_DEPRECATIONS_CHANNEL=null
LOG_LEVEL=debug
LOG_SINGLE_PATH="storage/logs/laravel.log"
LOG_DAILY_PATH="storage/logs/laravel.log"
LOG_EMERGENCY_PATH="storage/logs/laravel-emergency.log"

I would appreciate any help with this. :)
