I reverted back to Xcode 13.1 which I downloaded from the dev portal and am able to build and submit from that totally fine! You can have multiple versions of Xcode on your Mac without any downsides afaik as long as you name them different things (I named this one Xcode-13-1). Might be worth a try for others as long as you don't need anything 13.2-explicate:
