UPDATE: Found that this bug is a vanilla game bug thats been happening way before WOTC. Still not sure whats causing it but since deactivating the cloud the mind perk that was unused, the bug now happens with other unused perks associated with the Psi Ops class. So i went and disabled all the unused perks to see if that helps. List is below.

-PerkPackage="Perk_Psi_Aether_Shift"
-PerkPackage="Perk_Psi_Cloud_the_Mind"
-PerkPackage="Perk_Psi_Dissonance"
-PerkPackage="Perk_Psi_NullShield"
-PerkPackage="Perk_Psi_Mindblast"
-PerkPackage="Perk_Psi_Precognition"
-PerkPackage="Perk_Psi_Shield_Projection"
-PerkPackage="Perk_Psi_Void_Adept"


Worth noting... it seems that the Rising Tide mods use some of these perk names. Some I've talked to say they have never had any issues with the Rising Tide mods either. But if you are using those mods and having this crash... something in that mod combined with another mod might be triggering the crash. I assure you that it is not any of the CX enemy mods causing the crash.
