librealsense	2.55.1 RELEASE
OS	Windows

Intel RealSense Viewer / Depth Quality Tool has crashed with the following error message:

RealSense error calling rs2_create_context_ex(api_version:25501, json_settings:{):
    failed to convert special folder: errno=42

Hi @admin123yan My Intel RealSense colleagues provided advice about the errno=42 problem.

In SDK 2.55.1 there was a pipeline context crash problem due to an uninitialized json variable. The issue was fixed on the development branch of the SDK and also included in the 2.55 release. But sometimes 2.55 still has a problem due to mixed libraries.

Clean the folders and make sure that you have the correct version of the SDK libraries. Builds made from the development branch didn’t have the problem after the fix.

Another possible cause of the error is that the SDK uses a json file to store settings. Sometimes, due to an app not cleanly closing down, those json files are empty and the SDK will crash on the next time that it is launched. The json files can be found at the following location on a Windows computer:

C:\Users\[user]\AppData\Roaming

The folder contains files like 'realsense-config.json'. The workaround is to delete the empty json files at this location and then relaunch.

嗨@admin123yan 我的 Intel RealSense 同事提供了有关 errno=42 问题的建议。

在 SDK 2.55.1 中，由于未初始化的 json 变量，存在管道上下文崩溃问题。该问题已在 SDK 的开发分支上修复，也包含在 2.55 版本中。但有时 2.55 仍然会因为混合库而出现问题。

清理文件夹并确保您拥有正确版本的 SDK 库。修复后，从开发分支构建的版本没有出现问题。

错误的另一个可能原因是 SDK 使用 json 文件来存储设置。有时，由于应用程序未干净关闭，这些 json 文件为空，SDK 将在下次启动时崩溃。 json 文件可以在 Windows 计算机上的以下位置找到：

C:\Users\[user]\AppData\Roaming

该文件夹包含“realsense-config.json”等文件。解决方法是删除此位置的空 json 文件，然后重新启动。
