Wireshark freezing when restart/show options/List interfaces after stop the running live capture using PIPE file feed data

I use "wireshark -k -i pipeFileName" to launch wireshark, My application feeds data to wireshark using pipe file. I stop the running live capture using "Stop" button, When I perform other operations, like "restart/start live capture/show options/List interfaces", Wireshark always frozen. is it a bug??
