OCB: StartImage failed - Aborted (Intel DH67CL)

Hi! I am trying to install Monterey 12.7.5 with a PC that has the following specs:

• CPU: i7 2600
• MOBO: Intel DH67CL
• RAM: 10Gb DDR3
• iGPU: Intel HD 2000 (disabled in BIOS due to incompatibility with Monterey)
• dGPU: ASUS RX 580 8Gb
• Storage: Crucial BX500 240Gb + 1Tb WD BLue
• Audio: PreSonus Studio 24C
• Bootloader: OpenCore 0.7.0

Context:

A couple of days ago I had tried to install Monterey with Clover. Indeed, I got it:

However, when trying to start the installer from disk, I got a lot of errors until I decided to try OpenCore, followed Dortana's guide and used OC version 0.7.0 because I saw someone running his Hackintosh with the same motherboard using this bootloader.

Now, I haven't had much luck with OpenCore on previous occasions, but now I managed to get it to boot from USB with no problems (however, if there is anything I could correct, I would appreciate your help as well)

After this, boots without any problems... or so I think.

I don't get any GUI, with icons and stuff (unlike Clover which did show me a graphical interface), I just have this:

It even recognizes the macOS installation on the hard disk (option 4).

The problem is that, when I select both start from USB and hard disk (option 3 and 4 respectively), I get the error:
OCB: StartImage failed - Aborted

OCB: StartImage failed - Aborted

After that, I return to the OpenCore selection/picker menu.

My BIOS:

• UEFI: Enabled
• VT-X: Enabled
• VT-D: Disabled (and I can't change that)
• SecureBoot: Disabled
• CSM: Disabled
• Sata mode: AHCI
• iGPU: Disabled
• HotPlug: Disabled

Things I did (or tried):

• Follow as closely as possible the Dortana guide for Sandy Bridge processors.
• Format the USB in FAT mode and MBR partition scheme (I used two different USB's).
• I used SSDTTime to extract the DSDT.aml file, which leaves me with only one SSDT-EC file that I added to the ACPI folder.
• I used GenSMBIOS to (obviously) generate my SMBIOS (MacPro6.1).
• I used ProperTree-Master to modify the config.plist file (taken from Opencore Release 0.7.0) and did OC Snapshot every time I made a change.
• Using a .raw image file from Monterey vanilla (I downloaded several .iso versions that I could not flash on any USB, both with Rufus and BalenaEtcher).
• Search a lot of times everywhere about every error I get...

I thank you in advance for any help you can offer me. I will attach the latest .log of Opencore and my config.plist
