Kernel Panics after installing OpenCore. Help needed

Hi there. I'm suffering from Kernel Panics after finally migrating from Clover to OpenCore. I'll try to explain all the details here:

Hardware:

  • Gigabyte z87x D3H
  • i5 4670k Haswell, 16GB RAM (tested several times during the years without issue)
  • Radeon 580 8GB and iGPU enabled.
  • iMac 14,2
  • 1 SSD for MacOS Catalina, with OpenCore 0.62 installed with the official guide from this sub (Dortania), following the guide and the Haswell recommendations to the point.
  • 1 HDD for Windows 10
  • All of the hibernation features are disabled.
  • Used Onyx to clean all system caches to clean any potential issue from MacOS.
  • The KP happens after resume from sleep. The screen freezes, it doesn't restart.

The last two kernel panic reports I had since I installed OpenCore look a bit different than the previous ones I had from Clover, I'll paste the last one here:

The time the process corresponding to the thread was Firefox, but it's a different one each time, so I don't think it's because of Firefox.

Any help will be VERY much appreciated
