Resolution

This is a known issue currently impacting vSphere 6.7 and 7.0. Engineering team is working on a fix and will be available in a future release of vSphere 7.0

Workaround

Set Latency Sensitivity set to Normal and then increase the memory. Once done set the Latency Sensitivity set to high and power ON the VM
