to fix this with the included juce(this was fixed in the develop branch) add #include to juce_StandardHeader.h located in src/deps/juce/modules/juce_core/system/

[CarloCattano]

#include <utility> did the trick Thanks to bacon Paul (surge team) at the unfa discord for pointing it out https://forum.juce.com/t/missing-header-in-juce-componentpeer/51665
