Crashing in Simulacrum and Delirium

I've been trying to semi-AFK farm Simulacrum maps but keep crashing every wave or two, my friend tried logging in the same character and running the map and he crashed too.

I have tried making my character move around(even though it doesn't have to), and it seems like it reduces the odds of crashing, but it still crashes.

This happens in Burial Chamber map when I enter the Mirror of Delirium too, and as I ran several Simulacrum, it happen with so many maps.

its same for me, is literally 1 crash per wave

the same problem
