Unity has updated Unity6000, but when I use this version of the engine to build for the vision os simulator, there will be many errors related to il2cpp_codegen. Does anyone know why?

Someone else here may have suggestions that are able to help you with this problem regarding Unity's library, but you should also check with the support resources provided by Unity to get assistance with their software.
I'm not sure why this happens, but I found that deleting the redefinitions allowed me to complete my build.
