Rivals disconnect mid-game — match under review, no loss or win (PC)

Every Rivals match on PC disconnects around minute 20-40. The game freezes for a second, then says "You have disconnected – match under review." No win or loss is recorded.

I've already:
- Verified game files on Steam
- Cleared EA App and Windows cache
- Reset network (flushdns, winsock reset)
- Reinstalled GPU driver
- Disabled all overlays
- Tested both wired and mobile hotspot (same result)

Internet is stable (no packet loss, 40 ms ping). Problem started after latest patch. Looks like a server/session bug; many players are reporting the same issue. Please escalate.
