php fopen() No such file or directory for file created in same process using Symfony/Component/Process class

Question

I am trying to make mysqldump backup and upload that backup to aws s3. everything is working separately but when trying both in a single script then the file is not found by fopen even file_exists is not able to read the file. please, someone, help. here is the code

function db_backup($db)
{
    date_default_timezone_set("Asia/Kolkata");
    $DBUSER = env('DB_USERNAME');
    $DBPASSWD = env('DB_PASSWORD');
    $today = date('YmdHis');
    $output_file = "{$db}_{$today}.sql.gz";
    if (!is_dir(storage_path('backups'))) mkdir(storage_path('backups'));
    $path = escapeshellarg(storage_path("backups/{$output_file}"));
    $process = new Process(
        sprintf(
            'mysqldump --routines=true --compact --comments=false -u%s -p%s %s |gzip > %s',
            escapeshellarg($DBUSER),
            escapeshellarg($DBPASSWD),
            $db,
            $path
        )
    );
    try {
        $process->run();
        if ($process->isSuccessful()) {
            if (file_exists($path)) {
                //$aws = resolve(S3Service::class);
                //$aws->upload($path, $output_file);
                Log::info("Daily Backup Successs {$path}");
            } else {
                echo "File Not Found: {$path} \n";
            }
        }
    } catch (ProcessFailedException $err) {
        Log::error('Daily Backup Failed', (array) $err);
    }
}

always getting File Not Found, but backup is successful.

Problem is solved by just removing escapeshellarg() function from file path. because of that function fopen was not able to read that path.

function db_backup($db)
{
date_default_timezone_set("Asia/Kolkata");
$DBUSER = env('DB_USERNAME');
$DBPASSWD = env('DB_PASSWORD');
$today = date('YmdHis');
$output_file = "{$db}_{$today}.sql.gz";
if (!is_dir(storage_path('backups'))) mkdir(storage_path('backups'));
$path = storage_path("backups/{$output_file}");
$process = new Process(
    sprintf(
        'mysqldump --routines=true --compact --comments=false -u%s -p%s %s |gzip > %s',
        escapeshellarg($DBUSER),
        escapeshellarg($DBPASSWD),
        $db,
        $path
    )
);
try {
    $process->run();
    if ($process->isSuccessful()) {
        if (file_exists($path)) {
            //$aws = resolve(S3Service::class);
            //$aws->upload($path, $output_file);
            Log::info("Daily Backup Successs {$path}");
        } else {
            echo "File Not Found: {$path} \n";
        }
    }
} catch (ProcessFailedException $err) {
    Log::error('Daily Backup Failed', (array) $err);
}
}
