解决方案 #

• 清理残留文件
  1. 删除项目根目录 Plugins 下的 RiderLink 文件夹
  2. 删除项目的 Intermediate 和 Binaries 目录，清空UE缓存
• 适配RiderLink版本
  1. 打开Rider设置：File > Settings > Languages & Frameworks > Unreal Engine
  2. 确认RiderLink版本与UE5.4兼容，若不匹配，手动下载对应UE版本的RiderLink插件，解压后复制到项目 Plugins 目录
• 修复Dotnet环境
  1. 运行UE安装目录下的 Engine\Binaries\DotNET\UnrealBuildTool\Build.bat 修复依赖
  2. 确保系统安装了DotNET 6.0或更高版本（UE5.4要求）
• 重置Rider配置
  1. 删除项目根目录下的 .Rider 文件夹
  2. 重新在Rider中配置Unreal Engine路径，指向D盘的UE5.4安装目录
