Apex legends not launching

I can't play apex legends on my pc because it's not launching though I never had this problem like a year ago when i last played apex on my pc. I also saw on the internet and other forums that i'm not the only one who has his problem. I also tried every possible solution to fix this problem because i thought there is a problem with my pc but no it wasn't because nothing worked even after i reinstalled my windows. Please fix the problem already.
