We also have the same crash on iOS 15.4 and 15.4.1.

I was able to resolve it by attempting to submit an older uploaded version and then canceling as soon as that step was completed. Then I tried to upload the new version again, surprisingly it passed that check ✅. If this process fails try to restart the mac. Hope it helps.
