What is your host OS, what is your guest OS, and which specific version of Workstation are you running?
Host hardware spec? VM hardware spec?
An official what?
I am a VMware employee and a volunteer moderator, but regarding your issue I’m just someone trying to help - getting you to share that information was a good starting point.
VMware Workstation running 40 VMs and 80 vCPUs sounds like a lot to me. You may have a use case for ESXi rather than Workstation, what workloads are your VMs running?
