Using the forum to report crash issues does not lead to a resolution in most cases, unfortunately. If you’re able to reproduce this crash, could you please submit a bug-report following the advice given in this document?

Submitting the bug-report allows Unity Technologies to look at the issue and repair their software. Unity should never crash, regardless of what one is doing.

It doesn’t crash on any test device or in the editor, so the best I have is that log. I can’t submit a full bug report as the project is >100gb, contains sensitive information and I’ve not found a way to reproduce this so I can’t give any guidance.
