ReganX, you are right, but it seems to be a silly plot hole, i mean if arthur only is able to wield it, then it should magically stop others from wielding it and Arthur only wields it in season4 finale for the first time.

Not necessarily. I got the impression that Kilgharrah thought that Arthur was the only one who was meant to wield Excalibur, not that he was the only one who was physically capable of doing so.
