I am getting the same error. I already tried to extract OVA and select OVF with the multiple files, however, I'm still getting that error. I just opened a TAC case and will share when we have this resolved.
It seems the answer is here... https://www.linkedin.com/pulse/how-deploy-vmware-virtual-machine-from-ova-directly-local-gabra-1/
I'll try that in my lab and share my results here.
