Game freezes seconds into a raid on Customs

I had this problem on different raids only on Customs: the game loads, I walk a few steps and then it freezes and I can only force close the game. I am using SPT Realism with everything disabled except for different bots behaviour, but this happened even before I installed the mod.

It's the bots spawning around the map.

This only happens on Customs though, no freezes on even bigger locations like Woods or Interchange, even with the "enable PVE" option not checked
