I am experiencing an issue when trying to start a capture in Wireshark on Windows. Every time I attempt to start a session, I get the following error message:

"The capture session could not be initiated on capture device '\Device\NPF_{...}'. (Generic error)"

What version of Wireshark is this? I'm not seeing a code path in Wireshark 4.6.x or 4.4.x, or in the development 4.7.x release, that would produce the error string "Generic error" (that corresponds to the libpcap/WinPcap error code PCAP_ERROR, which should always cause Wireshark to display a specific error string returned by libpcap/WinPcap, not "Generic error")
