HtoA constant segmentation faults

[Rory_Oday]

I am using HtoA 5.2.1, Houdini 18.0.416, I get constant segmentation faults whenever I render more than one frame. I am using RTX 2070, i5-4690K, 24GB RAM, Windows 7. I dont have the same problem on other renderers but arnold is my favorite. All my crash logs look somewhat different but here is an example. I tried reinstalling, updating my graphics card, increasing my TdrDelay... Nothing worked.

That looks like a crash while exporting the scene, not rendering.

Can you get Arnold logs for the frames?

Does this happen with any scene? Or just certain scenes? If just certain scenes, try removing geometry until it doesn't crash (to help isolate the problem).
