Sandy Bridge UEFI stuck on [EB|#LOG:EXITBS:START] while booting Monterey from USB

Hello guys, today I'm seeking for help.

I'm building a Monterey Hackintosh using Opencore v.0.9.5 (Debug version) with this hardware:

• CPU: i5-2500k
• Mobo: Asus P8P67 WS Revolution (so UEFI)
• 16gb DDR3 1600MhZ
• XFX Radeon RX550 4gb Double Dissipation (so according to TechPowerUP it should be the Baffin core version)

I compiled the SSDT-EC (the only one required since I have a 6-series chipset and UEFI support) with SSDTTime, and edited the config.plist according to the OpenCore guide.

I'm using the HfsPlusLegacy driver and these are the Kexts I'm using:

• AppleALC
• IntelMausi
• Lilu
• RadeonSensor
• SMCProcessor
• SMCRadeonGPU
• SMCSuperIO
• VirtualSMC
• WhateverGreen

The problem is that I'm stuck at the infamous [EB|#LOG:EXITBS:START] step while booting from USB.

I already tried to follow these steps but I didn't get any different result.

I also tried with Virtualization enabled and disabled (and therefore with DisableIoMapper set to False and True).

Despite not finding the CFG-Lock setting on the Mobo bios, I also tried with AppleCpuPmCfgLock set to False and True.

I honestly don't know what to try anymore guys, so I'd like any tip and insult you have.
