IntelMCHMonitor kernel panic on GA-Z490 on Monterey

[milmber]

Seeing kernel panics on my Gigabyte GA-Z490 Gaming X when using the IntelMCHMonitor.kext on MacOS 12.0.1 Monterey.

This worked without issue on Big Sur 11.6.1 and earlier.

Motherboard: Gigabyte GA-Z490M Gaming X
Bootloader: OpenCore 0.6.7
OS: MacOS 12.0.1
FakeSMC3 version: 3.5.3
IntelMCHMonitor version: 1.0.0d1 
Kexts loaded: AppleALC.kext , FakeSMC.kext, ITEIT87x.kext, IntelCPUMonitor.kext, IntelMausi.kext, IntelMCHMonitor.kext , Lilu.kext, NVMeFix.kext, RadeonMonitor.kext, USBMap.kext, WhateverGreen.kext
