Hey @SophieYe 
Welcome to the Postman Community! 
Are you using the Postman Desktop client while on a company VPN or behind a firewall? Has this been working in the past?
你解决这个问题了吗，我一直没有解决，已经好几天了
Would it be possible to extract your logs from the app and send them over to [email protected]?
Reference or link this conversation in the email so that we can track it, please.
It will give us a better idea of what might be happening for you here. 
I have just sent a email and attached my computer logs. Thanks for your attentions and hope to be helpful for you.
没有，一直都没有，我现在都只能用网页版，非常难过
我的不行，我已经升级到11.45了，还是一片空白
yep，I followed you advise, my version is 11.45.6. but, so sad, it still a blank page when I click on the “switch to workspace”.
你的意思是现在安装的版本可以看到顶部菜单栏吗？就像我图中这样。
如果是的话，你可以退出重新登录试试。
试了呢，退出登录、重新安装都试过了， 仍然是不行的，好悲伤啊
