VSCode中输入?函数无法打开R帮助文档求助

我正在用VSCode学习编写R语言，遇到一个问题：在R交互式终端输入?函数名（比如?sum）后，无法打开对应的帮助页面。错误信息截图如下：

我的环境配置：

• Windows 11 最新版本
• VSCode 用户设置：

{
    "code-runner.saveFileBeforeRun": true,
    "code-runner.saveAllFilesBeforeRun": true,
    "code-runner.runInTerminal": true,
    "accessibility.signals.lineHasError": {
        "sound": "off"
    },
    "accessibility.signals.lineHasFoldedArea": {
        "sound": "off"
    },
    "accessibility.signals.lineHasBreakpoint": {
        "sound": "off"
    },
    "accessibility.signals.lineHasInlineSuggestion": {
        "sound": "off"
    },
    "accessibility.signals.onDebugBreak": {
        "sound": "off"
    },
    "accessibility.signals.noInlayHints": {
        "sound": "off"
    },
    "accessibility.signals.taskCompleted": {
        "sound": "off"
    },
    "accessibility.signals.notebookCellCompleted": {
        "sound": "off"
    },
    "accessibility.signals.notebookCellFailed": {
        "sound": "off"
    },
    "accessibility.signals.diffLineInserted": {
        "sound": "off"
    },
    "accessibility.signals.diffLineDeleted": {
        "sound": "off"
    },
    "accessibility.signals.diffLineModified": {
        "sound": "off"
    },
    "cmake.configureOnOpen": true,
    "git.openRepositoryInParentFolders": "never",
    "accessibility.signals.progress": {
        "sound": "off"
    },
    "r.bracketedPaste": true,
    "r.rpath.windows": "C:/PROGRA~1/R/R-44~1.1/bin/x64",
    "r.helpPanel.cacheIndexFiles": "None"
}

我已经尝试执行VSCode中R扩展的Clear Cache & Restart Help Server操作，但这个操作一直处于运行状态，无法完成。

求可行的解决方案，谢谢！
