GitHub Extension for Visual Studio version: 2.10.8.8132
Visual Studio version: 2019(16.3.29519.87)

The Bug Used to be :
Login failed
Unable to retrieve your user info from the server. A proxy server might be interfering with the request.

Now The BUG is:

EROR [01] ServiceProviderExports    Couldn't find service of type GitHub.Api.ILoginManager
EROR [34] GitHubServiceProvider     Error loading GitHub.Services.IConnectionManager
System.InvalidOperationException: 由于存在死锁的高风险，不能从 AsyncPackage 派生类中的后台线程调用 GetService。应改为调用 GetServiceAsyn (无需在产生的“任务”对象上调用“结果”或“等待”)或在调用 GetService 之前使用 JoinableTaskFactory.SwitchToMainThreadAsync 方法切换到 UI 线程。
   在 Microsoft.VisualStudio.Shell.AsyncPackage.GetService(Type serviceType)
   在 Microsoft.VisualStudio.Shell.Package.System.IServiceProvider.GetService(Type serviceType)
   在 GitHub.VisualStudio.GitHubServiceProvider.TryGetService(Type serviceType)

Steps to reproduce the behavior:
There's no procedure, it just comes out of nowhere（He used to be normal!）
Open VS2019 ，Then Open Team resource manager

I expect him to get back to normal because this is all about my projects
