I'm sorry to see that also setting the ICED_BACKEND isn't helping 😞
You don't see any output because of #578, but actually it'd be interesting to see some error trace in this case...

Hey @swola I just built a new version of the app for you.

Here you are: Sniffnet_Windows_64-bit.msi.zip

It is built against commit 0c67e7e on the windows-debug branch, and using this one you should be able to see some logs in your terminal so that hopefully we can understand and fix the issue.

Thank you

It looks like libpcap returned invalid UTF-8 when list device or something wrong in CStr::from_ptr

I try to use pcap:Device in rust but failed,maybe it neet to install visual studio (I don't know how to use Rust)

Mm, it seems that your Npcap installation still have some problems.

Are you sure you installed Npcap in WinPcap compatible mode as described in the guide?
However, the Npcap SDK and visual studio are only required for the build, but you don't need them to run the .exe app.
Only Npcap is required.

Another thing you can do to solve the UTF-8 error is to check the box "Beta : use unicode utf8 format" in windows regional options, as described in #120.

Thank for you help it works by checking the box "Beta : use unicode utf8 format" in windows regional options

Awesome 🎉
Remember that now you can remove the ICED_BACKEND environment variable, because the default renderer will probably work better than tiny-skia.
