[ZM] Game Freezing/crashing at random times in co-op even with no scripts running

[one dollar]

Here are my most recent crash logs. in the most recent log, the only two custom scripts i was running were Custom Power Ups and Zombie Counter when this specific crash occured

things i have tried:
deleting plutonium appdata folder
running plutonium with no mods
verified ownership of black ops one and all other games on plutonium
re installing windows

this crash only happens in co-op, i can play singleplayer fine. i am playing with my wife who is on the same network as me (private match)

and to add i was able to play with scripts no issue before this started happening (3 weeks). i have also tried re installing black ops 1 from steam
