Catalina install stuck on [EB|#LOG:EXITBS:START]

I'm trying to install MacOS Catalina on my AMD Desktop but I'm getting stuck on [EB|#LOG:EXITBS:START]. I've tried to follow the dortania guide as accurately as possible but perhaps I've made a mistake somewhere. I have already looked at the following page addressing this issue to no avail. I have tried the following things:
  • Disabling Above 4G Decoding in the BIOS and adding npci=0x2000 to the boot args.
  • Enabling AppleCpuPmCfgLock and AppleXcpmCfgLock (and separately as well)
  • Manually creating SSDT-EC according to this guide
  • Disabling ProvideConsoleGop.
  • Enabling / Disabling DevirtualiseMmio, SetupVirtualMap & EnableWriteUnprotector in all possible combinations.

I have attached my config.plist and my latest OpenCore log file. Thanks in advance for helping :)
