Deadlock detected 【Party Play】

I am experiencing frequent game crashes with the "deadlock detected" error exclusively during party play. Solo gameplay is completely stable. The crash occurs randomly during normal mapping in a party (2-6 players). It is not tied to a specific zone or boss.

The client logs consistently show a specific synchronization error before the crash:
