ShadowsocksX-NG got crashed on my MAC.

[smeleAvon]

Five days ago,shadowsocks got crashed on my MAC.

Describe the bug
I've tried to reinstall this App, restart my MAC and all the other methods I can find on the web.
5 days ago(2020.2.13 and before), it can work very well.
I don't know what makes it break down. Recently I used my VPN to look through some pages like Google and Stackoveflow, install Redit with normal operations and nothing more.
After the crash on my Shadowsocks, I asked many of my friends to check the IPs I've got and they can make it right on iOS, Windows and Android, and I also tried to use brand new IP but it failed as well.

Expected behavior
I really want my Shadowsocks to work again, I know there must be some mistakes in my MacOS and I sincerely want to make it all right!
