我在 wps 的配置文件上设置了 deny network 和 deny unix。
从 htop 上看也在 enforce 状态，同一配置文件的其它限制也已经生效
但是仍未能阻止WPS连接网络。
如果不需要完整沙盒，只要禁止联网的话也可以试试 bwrap --dev-bind / / --unshare-net wps 来运行

This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.
Available platform plugins are: xcb.
