【问题描述】：
在 Windows 10 上，我试图通过适用于 Unity 2021.3.16f1 的 OmniSharp 获取 C# v1.25.2。但是，当我尝试运行 Visual Studio Code 时，OmniSharp 返回一条错误消息，指出“未找到符号”。
之后，C# intellisense 似乎可以识别一些关键短语，但通常会在 OmniSharp 日志中返回错误，例如“已收到“某些操作”的响应，但找不到请求”。在 void Update() 中键入 OnTriggerEnter2D 时，我还收到错误消息“名称‘OnTriggerEnter2D’在当前上下文 [Assembly-CSharp] 中不存在”——这是针对空白项目中的新 C# 脚本。
请注意，在错误开始发生之前，我最初让 C# 工作。在上次它工作和第一次不工作之间发生了几件事，包括我将文件目录重新分配给辅助硬盘驱动器、安装 GitHub 以及安装 Unity 和 C# 的更新。我不确定这些是否与问题有关。这是完整的 OmniSharp 日志：

Screenshot of the Error I Received
我努力了：
- 重新启动计算机
- 重新安装 Unity 和 Visual Studio Code 包
- 重新生成 Unity 项目文件 - 重新安装 VS Studio Code
- 确保我安装了适当的开发工具、.NET 框架和 SDK（我相信我目前使用的是 .NET v4.7.1，因为 Unity 但我并不完全有信心）。
如果有人能帮我解决这个问题，那将非常感谢，因为我找不到其他人遇到这个问题。
