Brawl Stars Username Changed to "Warrior" Without Any Action From Me

I've been playing Brawl Stars for a long time, and my in-game name has always been registered as "Erva Asel." About 30 minutes ago, when I logged into the game, my name was normal, but when I logged back in 5 minutes ago, I noticed my username had changed to "savaşçı" (warrior), even though I hadn't made any changes myself, and I'm currently unable to fix it back. I logged out and back in, but the problem is still happening the same way. I haven't lost any trophies, progress, or brawlers I own — only my name has changed on its own. Since this is both confusing and unsettling, I'd like the issue looked into and my username corrected back to "Erva Asel." I'm writing here because I don't know how to use the in-game support section. I'd appreciate it if my account could be reviewed, an explanation given for why the name change happened, and my name restored to what it was before.
