Executable crash and Zalmarath, the Colossus

Running a tier 2/3 map on a Forge map fighting Zalmarath, the Colossus as a ranger where I rely on my ST being Lightning rod + Lightning Arrow. It was clear that the lightning rod was not procing consitantly on the boss forcing me to go oom. The boss is not triggering the lighting rod on the platform thats right next to him.... If this is intended let me know and I will never run these nodes as its ridiculous.

Immediately following the completion of this boss the game itself froze and crashed stating some issue with the exe. This new league/season needs to be redone.

Let me know if there are any steps I need to do to fix this. I have already ran Steam's file integrity and reinstalled the game neither were a fix. No difference from HDD and SSD either.
