Crash when hitting Undo after converting materials

I'm running into a consistent crash in the 30.7 build. Basically, if I use the Cycles to Octane converter a few times (2 or 3 times) and then hit Ctrl + Z to undo, Blender instantly closes/crashes to the desktop. It happens every time, even in simple scenes.

Can you please provide a simple scene and the needed steps to reproduce the issue?
Thanks.

I have attached a video showing the steps to reproduce the issue. It happens specifically when I press Ctrl + Z a few times immediately after converting materials (using the Octane converter). It is random and doesn't happen 100% of the time, but I have encountered it with imported assets from various sources like Quixel, BlenderKit, and Sketchfab
