从AnacondaNavigator启动Spyder时出错-“chcp1252…1>nul2>nul”

我正在使用 Anaconda 使用 Spyder 在 Python 中进行数据分析。我一直在这样做，安装包，更新包/Spyder/等，但在更新 Spyder 后，我现在在从 Anaconda 中启动 Spyder 时收到一条错误消息。

C:Usersjdoe>chcp 1252
Active code page: 1252

C:Usersjdoe>call C:UsersjdoeAnaconda3Scriptsactivate C:UsersjdoeAnaconda3

(base) C:Usersjdoe>spyder  1>nul 2>nul

此终端窗口出现，然后关闭自身和 Spyder。

如果我从 Anaconda 中打开一个终端窗口并输入spyder，我就能成功启动该应用程序。但是从 Anaconda Navigator 启动失败，我不明白此错误消息或如何修复它，我也无法在搜索中找到与此问题相关的任何内容。任何帮助了解正在发生的事情以及如何纠正这一点将不胜感激。

conda info 如果有用，请报告：
