I am seeing the same issue. I had another developer try to submit the same build and they got the issue as well, but when they created a new build for submission on their end they were able to successfully submit. So I'm wondering if there is possibly some build issue on my end, but I'm not seeing any indication that is the case from App Store Connect. This is a build that we have distributed through Test Flight that we are now trying to submit for release.
