Interesting, I suppose you can prove that by temporarily bypassing that feature, that way you’d at least confirm that is the problem. I had a hunch on my project as well, I’m using a variation of the script mentioned in this post in order to populate the Transform property of a VFX Property Binder component on a VisualEffect at runtime:
I tested that theory yesterday by creating a standalone project that does nothing else but reproduce the functionality of this system, but unfortunately it functions just fine and I couldn’t repro the crash in it.
