This was an issue #2363 that was previously solved in the OpenDuetPkg, however it is no fixed for the OvmfPkg.
A new secure PE/COFF loader was introduce in the 0.8.8 release of OpenCore. When compiling the OVMF from the Acidanthera UEFI Development Kit (master branch) the firmware cannot load the latest HfsPlusLegacy.efi driver from OcBinaryData.
