I have the same problem, I cannot add a network adapter to a VM without the interface crashing and asking to reload.
This is the SECOND install of VMWare ESxi 6.5 in the last week.
6.5.0 5310538
I was unable to resolve the issue on the first host, so I decided to add another host instead of trying to fix VMware's problem.
I have used multiple browsers, Firefox, IE, even Opera, no change, they all crash.
This is for a development system so it is critical this works.
I have submitted a bug report for the crash, but I am still searching for a way to get past this.
Here is the error:
