My desktop environment is KDE Plasma 5.18.2, if I start this program directly, the Servers tab, Rules tab and Settings tab are empty just like these pictures: settings tab However, if I start it with root privilege by executing sudo /opt/v2ray-desktop/v2ray-desktop , the program works very well. Can anyone help me? Thanks.
