Solved: If anyone's facing a similar issue, I'd installed the USD package to enable me to export a model to QuickLook. Needed to remove in package manager before doing a distributable build.

Same issue here. Published successfully a year ago and now resubmitted with no major changes, only to get an error out of the blue - non-public API usage, binary errors etc. Then flags up something about STATE_ERROR_VALIDATION.10. Bitcode included as I see this has been a problem for some. Using Unity and XCode 13.3.1.
