Unfortunately this is an npcap issue, and you should raise the issue at their support site.

What you can try:

1. Stop Wireshark, uninstall npcap from "Apps", you may even need to reboot to stop everything using npcap before uninstalling it..
2. Reboot.
3. Install the latest npcap from their site.

If this still doesn't work, uninstall npcap and try installing the obsolete and unsupported WinPcap from here. Wireshark will use this if it can't find anything better.
