UE5 Source Build - Mass Entity plugin compiler errors?

I am using VS 2022, and installed all recommended prerequisites/tools to try to build UE5 from source. During compilation I keep getting errors coming from the Engine/Plugins/MassEntity/ module, and any files that reference it. This seems to cause the build to eventually fail. Does anybody have any fixes or know why these header files have compiler errors?
