【问题描述】：
我无法登录 Visual Studio Community 2017。如果我输入我的 Microsoft 凭据，则会弹出此消息：
我已经尝试过类似问题中列出的每一件事：Visual Studio 2017 - How to fix error: We could not refresh the credentials for the account
但它们不起作用（尝试删除 IdentityService 文件夹内容和文件夹本身；尝试通过安装程序修复）或无法完成（我无法访问“帮助”项菜单：没有登录整个应用程序被锁定）。
日志文件进入
我该如何解决这个问题？ C:\Users\user\AppData\Local\Temp\servicehub\logs\AadAccountProviderService-10304-v05lxa0n-1 显示：
