Frequent Crash with contagion

Hi,

I'm playing a Drain + Contagion build with my level 93 Lich.
Since the last update, I've been experiencing frequent crashes when encountering large packs of mobs on maps.
Sometimes there are big freezes, then the game resumes. More often, I'm sent back to the login screen, sometimes with the message "too many actions at once."
My teammate, when playing with me, experiences the exact same freezes and disconnections, at the same time.

The issue seems to occur a bit less often when I remove the Intensifying Agony support gem from Contagion, but it still happens—roughly one map out of three.
When it does, I lose my loot, my maps, my bosses, etc.

Im playing with a very good computer, on Paris server

In the current state, I can't really enjoy playing the game anymore.
After all the time I invested in this build, it's really frustrating.

Bump, also experiencing rubber banding when contaigion attempts to spread to a large number of mobs. Lvl. 90 poison/contagion Acolyte of Chayula.

Bump.

In a t15 unmodified map, gameplay "paused" for 15 seconds then crashed to login for "Performing too many actions" after Quarterstaff Strike into Contagion spread. Got moved to hideout on log back in, lost the map and waystone, but seemingly did not die or lose xp.

Same issue here. Also ED+Contagion. Tried changing to vulkan or dx12...no real diff. Really frustrating.
