NPCAP 0.995 gives duplicate packets

Hey @all,

on my Lenovo X1 Carbon with Wireshark 3.0.3 the npcap installer 0.995 results in every sent packet from my machine being captured twice, bit-wise identical with minimal time delta of a few microseconds only.

This happens on all interfaces (Wi-Fi, Ethernet, USB Ethernet) and google searches seen to confirm the issue see e.g. https://github.com/nmap/nmap/issues/1055 however - I do not have any workaround to solve the issue, not even disabling promisc. mode works.

I have not installed the loopback adapter or configured WinPCAP compatibility mode, since either or both options will break my Fibercom WWAN interface from working, so its quite frustrating - any hints or help appreciated
