VMware vCenter Converter Standalone 6.6.0.23265344 - Windows Server 2019
For the source VM, VMware Converter is receiving a value for numCoresPerSocket as zero. This value is an invalid input.
The VMware Converter is calculating vCPUs by dividing CPUs by cores. Since the number of cores is zero, the client is crashing with an invalid function of divide by zero exception.
The fix will be provided in the next VMware Converter release -- (6.6.x or above).
