I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

We're doing additional investigation in #13731 for Xcode 16. However, my suspicion is that the discussions in #12877 and #13718 are relevant.

[paulb777]

Based on #13731, our testing is showing that Xcode 16 works with the zip distro.

Please check that you're only using binaries from 11.2.0 and the instructions are followed. We'll need a fully reproducible example to help.

If you have more information that will help us get to the bottom of this, just add a comment!
