In our case, our app (deployment target of iOS 11) was hit with this issue when uploading a Bitcode enabled (or disabled) build that was compiled with Xcode 13.2 RC
Since we support iOS 11, we don't even use Swift Concurrency features so the issue came as a surprise to me. I tracked the problem back to the fact that one of our dependencies (RealmSwift) has some async code which while it wasn't used, it was enough for Apple to break our build when they processed it :D
We recompiled Realm of verion 10.14 and everything is ok
