I can confirm downloading the older xcode, 13.4.1, seems to resolve the issue. Tonight after my update was finally approved an hour or two earlier, I submitted an app update (2nd one today) at 7:57pm, it went "in review" at 8:15, by 8:18 it was approved, and by 8:20pm I got the 'accepted' messages. So, at least two updates today got through with the older xcode.

Me Too!
