Black screen after grub boot screen

Sorry if this has already been answered, but I have tried searching here and Google for a solution. I have the latest version of Proxmox running in a 5 node cluster. I have been using a product from StableBit for drive pooling, but am having constant issues with their software, so I thought to try TrueNAS Scale. I wanted to test in a virtual lab before tearing down an 80TB pool containing files and rebuilding it, however, I cannot get the VM to load TrueNAS Scale.

I have downloaded the latest TrueNAS ISO an built a VM with 64 GB of RAM and 8 cores along with a couple of 1 TB virtual drives to test. I boot the system, see the grub loader screen and then the screen goes completely black and is stuck.

Any ideas what I am doing wrong?
