10010 error plz help me

I paid 100 euros for lost ark
But after their release I can’t play the game.
I tried all of them.

Exemple : unchecking Ipv6, flushing dns, TS1, changing the network source (I don’t have a mobile hotspot, but I do have my main internet and its 5g variation and tried both wifi and ethernet cable), google dns, manual port forwarding, integrity checks, reinstall, and writing the letters h-e-l-p with sticks.

but i still can’t play the game
I think Lost ark cheated on me. give me back my money
