I think this is a dupe of #60276. Please use the latest 5.7 or main branch toolchain to verify and close. /cc @theblixguy

The fix was merged a bit late into the 5.7 branch, so it didn't make the cut for Xcode 14 or 14.0.1, but I can verify it's fixed on Xcode 14.1 beta.

I verified it fixed on Xcode 14.1 RC (14B47). Thx, @theblixguy !
