Hello to you too, Shlomi. 
Yeah, I learned that when you mentioned Epic games in your post. But I am asking you the spec of your PC. Things like how much ram it has, which graphic card it uses, etc. It could be that your PC doesn’t meet the minimum requirement of the game.
Have you made a reply on the above thread and posted your issue yet? I’d like to ask you to click on the thread, follow the format which the OP provided, and click the reply button there. It’s more likely for them to know your issue there rather than here.
