Magma Barrier with Fiery Death will crash my teammate in same map

I am using a "Magma Barrier" Build with support gem "Fiery Death". If my firends play with me in same map, they will crash and shut down the POE2 instantly when I trigger the skill explode emeny. And we found that if we in the same area, it means they can see the skill explode, crash will not happen. The crash will only happen if we walk separately and they cannot see my skill trigger.
