vscode intellisense自动完成和提示均不起作用

Question

我试图重新安装win10系统并重新安装vs代码。它仍然不起作用。 我已经安装了所有扩展程序。但是，智能感知不适用于任何语言。

这是我的setting.json

{
    "editor.quickSuggestions": {
        "other": true,
        "comments": false,
        "strings": true
    },

    "files.autoSave": "afterDelay",

    "editor.acceptSuggestionOnEnter": "on",

    "editor.snippetSuggestions":true,
