Fortnite suddenly in Arabic?

I do not play Fortnite anymore, but I recently let my little cousin play Fortnite. But when he turned on the game, everything was suddenly in Arabic. I'm afraid that the account was stolen or something. Is that normal.

I think your cousin has allowed himself a little prank.

Plus, if someone else from another country logs into your account, you'll be notified by email.

I hope you know where to change the language back.
