That known issue occurs on a Windows 10 PC running version 1903 when two conditions are present:
First, the diagnostic data level setting is manually configured to the non-default setting of 0. For those who don't understand how unusual that configuration is, note that it applies only to Windows 10 Enterprise and that it can be set only using Group Policy on corporate networks or by manually editing the registry.
You can't accidentally enable this setting. And you can't deliberately set it on a system running Windows 10 Home or Pro, because it is for Enterprise edition only.
Second, the bug occurs only when a VPN profile is configured as an Always On VPN (AOVPN) connection. That's a specific form of virtual private network (VPN) access that was introduced with Windows Server 2016 and requires a tremendous amount of network configuration to enable. You can read the gory details here:
Remote Access Always On VPN.
But unless you're a Windows Server 2016 sysadmin, it might not make sense. And as one commenter observed below, "I think I'd rather be beaten to death by my own keyboard than have to set up AOVPN."
[...]
It might also be worth noting at this point that this is an optional update. It's not installed automatically. It is literally a preview of the July cumulative update, released at the end of the previous month for corporate customers to test. Those tests by enterprise customers involve configurations like these on targeted devices, and until those issues are resolved no enterprise will consider the current release ready for widespread deployment.
