使用拳头切号之后拳头客户端每次都初始化

使用一次拳头切号，出现需要输入账号密码且界面变为英文，修改语言后勾选保持登录后手动登录。再退出拳头客户端再打开，发现拳头客户端无法记住登录状态，且设置被初始化（语言变为英文，勾选开机自启），修改后再次打开仍然会初始化并无法记住登录状态。严重bug。重新安装拳头客户端也没用，自此拳头客户端每次打开都初始化需要手动输入账号密码。

The report provides reproduction steps for the Riot client resetting its language, startup setting, and login state, but names no source file, test, or entry point. First reproduce the behavior after switching accounts and relaunching the client, then trace the affected settings and session persistence; done means the client retains the selected settings and login state across restarts.
