突然，git fetch，push，pull，clone等命令停止工作。首先，它出现在Visual Studio的Team Explorer中，然后尝试了cmd，PowerShell和Git Bash。只有Git Bash在起作用。我尝试重新安装Visual Studio，Git，Git Credential Manager。我还从Windows的用户帐户和其他位置删除了所有缓存的凭据，还尝试了更改凭据助手。 Powershell的输出为：
error: waitpid for git credential-manager get failed: No child processes
error: waitpid for git credential-manager store failed: No child processes
error: waitpid for git credential-manager store failed: No child processes
Visual Studio的输出是：
Fetching from origin
Error encountered while fetching: Git failed with a fatal error.
'credential-manager' appears to be a git command, but we were not
able to execute it. Maybe git-credential-manager is broken?

'credential-store' appears to be a git command, but we were not
able to execute it. Maybe git-credential-store is broken?
