Menu bar always get stuck when reopening the lid and trying to connect to the network
After updating to macOS 10.14.6, I find that everytime I reopen the lid of macbook pro, it cannot connect to the network. And if I click on the network icon in the menubar, the menu bar gets stuck. The network preference window is also not responding, so I have to restart my macbook pro each time. I think it is due to a firmware problem and is there any suggestion to solve it other than downgrading the os version?
