Strongboxes causing client to crash

I'm running containment scarab strat for 16.5 maps

whenever I turn on one or two box after that it's crashing.

I don't know what's wrong game was running just fine until I started playing this strat.

AMD RYZEN 5900X
NVIDIA RTX 3080
64GB RAM


Maps I'm trying to run:

around 190% quant 16.5 maps
one of each ambush scarabs
full map modification atlas mod with ambush


I had a theory yesterday when my merc is in the map crashes way more frequent but later today I've started seen crashes without merc too.

I don't know why this is happening... Maybe some of the new 16.5 map monsters have wrongly codded into containment and when I click on them it crashes the client?

Hi anyone will assist me with why this is happening?
