I can confirm the same issue with Ventura and it's also fixed as @bariscukur14 did.

Xcode 14.3.1. You can set the minimum deployment target to lower manually.

The odd thing is that I'm using CheckedContinuation on another project with same target and similar style: project is mostly ObjC with added Swift, and newer async stuff in @objc classes marked with @available(macOS 10.15, *). It builds in release mode without issues.

That's correct. The thing I'm worried about is all the authorisation dialogs (minimum 1, up to 3 I believe) that the customers will have to go through again. They did that when they installed our product and they won't be happy to do the same chore again, specially because some machines are in remote locations they don't have frequent access to. I take it that there's no way to use accessibility feature to automatically push those "Allow" buttons?
