I am trying to build my plugin on macOS with Xcode 14.3 and I am getting this error:

I am using SDK 3.7.5 (I did check the release notes for 3.7.6 and 3.7.7 and did not see any changes that makes me believe this is the reason why it fails).
On an older mac with Xcode 13.2.1, it compiles perfectly.
Any idea what could be wrong? Clearly not understanding std::move() is definitely something really really odd going on…
