Need Help For Steam

Hello friends. Hopefully, you are all well. This is my first post in this forum. And I don't know this is the right place or not to post this. But I hope I will get a better suggestion from you. I am a big fan of Steam games specially "Elsword". But my Steam problem is a little different. After several attempts, I am unable to launch 'Elsword' on Steam Steam. Although, I am not an expert on this matter. Can anyone provide any suggestions? Any help will be appreciated.

So, I found a solution from here after searching on Google today. Guys, I don't know how much it will help me or not.
