Look at the pull request. Instead of using the latest available files for OVMF_CODE.fd and OpenCore.qcow2, he's using the ones from that specific commit.
Which works.

I had to do the same thing: navigate to that commit and copy those files manually, only then i was able to launch the VM.

(just to say that the problem is still present)

In your home dir, create a file called fix.sh with the following content.

OSX_KVM_COMMIT="da4b23b5e92c5b939568700034367e8b7649fe90"
wget "https://github.com/kholia/OSX-KVM/raw/${OSX_KVM_COMMIT}/OpenCore/OpenCore.qcow2" "${VM_PATH}"
wget "https://github.com/kholia/OSX-KVM/raw/${OSX_KVM_COMMIT}/OVMF_CODE.fd" "${VM_PATH}"
if [ ! -e "${VM_PATH}/OVMF_VARS-1920x1080.fd" ]; then
  wget "https://github.com/kholia/OSX-KVM/raw/${OSX_KVM_COMMIT}/OVMF_VARS-1920x1080.fd" "${VM_PATH}"
fi

Run the script:
sh fix.sh

Wait for the downloads to finish, you should have 3 files in your home dir.
OpenCore.qcow2, OVMF_CODE.fd and OVMF_VARS-1920x1080.fd

In my case, I was installing Big Sur, so I had to move the files to the directory macos-big-sur:
mv OpenCore.qcow2 OVMF_CODE.fd OVMF_VARS-1920x1080.fd macos-big-sur/

Rerun quickemu command.
