When I try to run UE 5.6.1, or UE 5.8 (Built from Source Code), I get the following metal error:

I have tried modifying the Apple_SDK.json and setting the Max versions to 26.0.0 and LLVM versions are fine.
I tried building u5_main source as well and get the same result. It builds fine, but when it goes to run same thing.
I have tried manually installing the Metal SDK from Xcode Directly, and from command line to no avail. I also tried the various hacks and tricks for the beta versions that I found in different forums.
Here is the Metal Toolchain information:
Metal Toolchain 26.0 (17A324) [com.apple.MobileAsset.MetalToolchain: 17.0 (17A324)]
(Installed)
Here is the Apple_SDK.json config:
{
"//1": "Xcode versions:",
"MainVersion": "15.2",
"MinVersion": "15.2.0",
"MaxVersion": "26.0.0",
"//2": "!!!",
"//3": "NOTE: If you update the MaxVersion, double check the AppleVersionToLLVMVersion array below!!!",
"//4": "!!!",
"//5": "The versions on Windows are iTunes versions:",
"MinVersion_Win64": "1100.0.0.0",
"MaxVersion_Win64": "8999.0",
"//6": "This is not a version range, but a mapping of Xcode clang versions to LLVM versions, for shared version checks with other clangs",
"//7": "Version mapping can be found at https://en.wikipedia.org/wiki/Xcode#Toolchain_versions",
"//8": "The first half of the pair is the first version that is using the second version source LLVM",
"//9": "For instance, Xcode 16 uses LLVM 17.0.6",
"AppleVersionToLLVMVersions": [
"14.0.0-14.0.0",
"14.0.3-15.0.0",
"15.0.0-16.0.0",
"16.0.0-17.0.6",
"16.3.0-19.1.4"
]
}
Any ideas?
