I couldn't figure out why Cargo wouldn't import into Blender. When I looked for console output, I found this:
``
[CARGO][ERROR] Exception occurred while processing import requests: bpy_struct: item.attr = val: enum "Input - Generic - sRGB - Texture" not found in ('ACES2065-1', 'ACEScct', 'ACEScg', 'AdobeRGB', 'ARRI LogC / AlexaWideGamut', 'Invert ACES 1.0 SDR-video', 'Log film scan (ADX10)', 'Panasonic V-Log / V-Gamut', 'Raw', 'RED Log3G10 / REDWideGamutRGB', 'scene-linear DCI-P3 D65', 'scene-linear Rec.2020', 'scene-linear Rec.709-sRGB', 'Sony SLog3 / SGamut3', 'sRGB')
``
I am using Redshift's OCIO config file (via an OCIO environment variable) and it broke Cargo by having Cargo tell me it couldn't find my 3D application - a misleading error.
