【POE2 bug】The game crashes after killing the BOSS in the Bronze Castle map in the other world map

Hello, I am in the Bronze Castle map in the other world map. After killing the final boss, the game suddenly crashed and exited. After restarting the game and logging in, I cannot enter the boss challenge area again and cannot pick up props. The same situation has occurred twice in a row. I don’t know what the reason is. How can I solve it?
