Walled City boss battle bug

Hello GGG Team, I was fighting the Bronze Walled City at 4:04 pm today, and the boss died, and I also died, but because the boss battle will teleport to another space, I can't teleport after I am resurrected, so I can't pick up these dropped props, and I can't wait for solutions online!! Is there any way to teleport back to the boss room or any other solution? Thank you very much！！
