Your output shows npcap is installed, albeit a slightly out of date version (0.996 is available).

I also suffered this issue yesterday and I fixed it with the following:

  1. Stop Wireshark\tshark\dumpcap etc. Basically anything that could be using npcap.
  2. Uninstall npcap from the "Apps" settings dialog.
  3. Reboot.
  4. Install npcap 0.996.

thank you, I updated npcap to 0.996 and it is ok now.

Note that "reboot" is an important step - one bug in the 0.995 release is that uninstalling it can crash the system; if you try to upgrade to 0.996 from 0.995, the installer will recommend that you disable Npcap and reboot, and will do that for you if you tell it to. Disabling Npcap before uninstalling will prevent the crash.
