POE2 Unable to exit the map boss scene

When the burial bog（中文译名 埋葬沼泽） swamp contains the map boss, I can't get out of the arena (boss scene) after the completion of the map boss, and I can continue to brush after shutting down the game and re-logging to the beginning of the map. If you need a special way to get out of the arena, the instructions for this are not good, I did not find any tips for getting out.
