Try updating to Npcap 1.30 using the 1.30 installer on the Npcap Web site. Even if that doesn't fix the problem, it might improve the error message to indicate more precisely what the problem is.
If it doesn't fix the problem, report it as an Npcap issue on the Npcap issues list. Give the full details of the error message - with 1.30, there may be a colon, and an error string containing a message and a number, after "failed to set hardware filter to non-promiscuous mode", so provide all that information. Also, provide all the information you provided above.
