I solved the issue like this: 
foreach my $key (keys %hashEntries)
{
    my @temp=$hashEntries{$key};
    
    #print "Elements: ".@temp."\t";
    
    print "[After no dump] Test 2 $key ->\t";
    foreach my $element (@temp)
    {    
        if($element ~~ /ARRAY/)
        {
            print "Array détecté...\t";
            foreach my $autreelement (@$element)
            {
                    print "[@$autreelement]\n";
                    $lesdomaines.="@$autreelement";
                    $lesdomaines.="\t";
            }
        }
        else
        {
            print "[@$element]\n";
            $lesdomaines.="@$element";
            $lesdomaines.="\t";
        }
    }
    print $key."\t".$lesdomaines."\n"; 
    $lesdomaines="";
}
