Ranked Mode High Ping 300ms Bug - Account Stuck in US Session - Case 237672095

Hi, I am experiencing a persistent high ping issue over 300ms ONLY in Ranked Mode, while my friends in the same party have a normal ping of 50ms.

Main Menu / Firing Range / Public Match: Normal Ping (30-50ms on Tokyo servers).

Ranked Match: Constant 300ms+ Ping (Seems like it is connecting to US servers).

Case Number: 237672095

I have already done all troubleshooting:

Cleared all launch options and reset local config files.

Reinstalled the game and verified file integrity.

Reset Windows network settings and router.

Tested with a Mobile Hotspot (Different ISP) - Still 300ms in Ranked.

Used ExitLag to force Tokyo routing - Still 300ms in Ranked.

It is clear that my account session is hard-locked to a US data center on the server side. Please manually reset my account regional session data or sync my Ranked profile back to the Tokyo/Asian region.

My other account works fine with 50ms on the same PC, only my main account has this issue
