Plz help.I cant use Intel RealSense Viewer / Depth Quality Tool

[1193361084]

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

[MartyG-RealSense]

Hello, a problem with the 'special folder' might occur if your Windows PC does not have a Documents folder in your user files directory. If for example your Windows user name was 'Fred' then your Documents folder might be at the following location:

C: > Users > Fred > My Documents

If there is not a My Documents folder in the username directory (e.g Fred) then you can try creating a new folder called My Documents in it.

Please see #5707 (comment) and the comments beneath it for more information about this problem.

Hello, do you require further assistance with this case please? Thanks!

Thank you!

My Intel RealSense colleagues have provided some further advice about the errno=42 error.

Given that the problem seems to be related to certain charcters being used in a Windows user account name, I asked whether creating a secondary Windows user account with a name that has no special characters might help. This was their response.

You can try to run it as Administrator instead of switching the account. On Windows 11, it also has a feature to run the app as a different user. That option can be enabled with the instructions at the link below:

Hey @Dm1stry @1193361084

We've recently fixed an issue about the "errno=42" error, which would happen if the user's name on that machine contained Unicode characters. Could you please check the development branch to see if this fix resolves the issue?

The PR with the fix is: #13597

The development branch can be found here: https://github.com/IntelRealSense/librealsense/tree/development
