Hi,
I'd say that that excludes the "it might be a hardware issue" for the most part. It's always possible that it is some combination in the hardware configuration triggering this, but it -at least- isn't due to failing hardware.
As for the lack of dump files, I guess you already verified the dump file settings. AFAICR they are set by default, but it doesn't hurt to check. https://learn.microsoft.com/en-us/windows-hardware/drivers/debugger/enabling-a-kernel-mode-dump-file
Re. VMware Support, I think we all agree on that it is a bit weird that it's not available for issues like this, but it is their choice to make. By default you get 30 days of email support, only if you explicitly buy support you can access their support for looking into issues like this.
Sorry I wasn't of more help.
