This doesn't look like a new crash, just a low-volume one. Something to do with the gradient cache, sorry I'm not specific but I don't know much about this code.

The recent crashes with this signature, such as bp-6258c640-5e17-4c2a-9a74-778580220716, seem to be missing crash reasons, which is odd.
