Capturing VPN Interface on Windows 10 black holes Traffic with Wireshark

I need to see if some issues that are occurring are due to the network, and want to start on the client to see why google speed test is failing over the VPN on the Windows 10 client. I admin the VPN gateway so I could do a more laborious capture there on my client but I would like to Wireshark capture the VPN adaptor interface. I can do this from the GUI but all traffic stops passing as soon as the capture begins, and starts again as soon as I stop the capture. Happens if I run as normal or admin user. Has anyone else seen this and got a workaround/solution?
