我突然无法在 Windows 11 上的 Rider（2024.1.3 / Build #RD-241.17011.166，构建于 2024 年 6 月 7 日）中调试一个项目（AvaloniaUI、C#、.NET 8.0.302），我正在努力解决这个问题。
如果我只是运行该项目，它会毫无问题地构建和启动。我在同一台机器上有其他解决方案，使用所有相同的技术堆栈，并且它们在 Rider 中调试时没有任何问题。所以它似乎仅限于 Rider 和这一特定解决方案。
在 VS2022 中打开这个有问题的解决方案也可以正常调试。一切都非常令人困惑，因为我昨天一整天都在处理这个项目（在 Rider 中），没有任何问题。
错误是：
One or more errors occurred. (One or more errors occurred. (CLR load callback is already in
error state. Error HRESULT E_FAIL has been returned from a call to a COM component. The
error code is E_FAIL, or EFail, or 0x80004005.))
您难道不喜欢这些神秘的 Windows 错误吗？似乎 0x80004005 在这里被精彩地描述为“E_FAIL 未指定的故障 0x80004005” 这里更一般地描述为：
Most generally speaking, error code 0x80004005 occurs when Windows cannot access a file or
folder. It is usually displayed as "Error 0x80004005: Unspecified Error."
我已经卸载并重新安装了 Rider，没有任何影响。
我尝试以管理员身份运行 Rider，但这没有帮助，我尝试删除所有 DotSettings 文件和 .idea 目录并重新启动。似乎没有什么帮助。
查看 Rider 日志文件，异常似乎是 Rider 调试器存在 COM 问题。但目前我如何解决这个问题还是个谜。为什么它只会影响这个解决方案？调试器与其他解决方案配合得很好。

更新：
此问题已通过 JetBrains here 和 here 提出。
总结似乎是作为单个文件发布是问题所在。
<PublishSingleFile>true</PublishSingleFile> <!-- breaks debugger -->
就像您在编辑中所写的那样。
SingleFilePublish我通过将 SingleFilePublish 包装在单独的 PropertyGroup 块中来修复它在我的项目文件中，并设置一个仅在调试时禁用 SingleFilePublish 的条件：
<PropertyGroup Condition="'$(Configuration)' != 'Debug'">
<PublishSingleFile>true</PublishSingleFile>
</PropertyGroup>
