Thanks Jason for the feedback!
This issue should be the known MTU issue which also mentioned by other folks (Txarly89, Jose noticed it too. Thanks All!)
Please expect the following update with the fix, and again, sorry for the inconvenience.
Thanks,

Hi William.
I have below problem with USB network adapter. System is installed with Esxi-6.5 update 2
I am not able to ping MTU size over than 1468 and above
