System Information
Operating system: Windows 8.1
Graphics card: AMD Radeon HD 7310

Blender Version
Broken:2.80-rc3 and 2.83.9
(example: 2.79b release)
(example: 2.80, edbf15d3c044, blender2.8, 2018-11-28, as found on the splash screen)
Worked: (optional)

Short description of error
Principled BSDF gives out this pink/purple tint when connected to image texture in rendered mode in lookdev looks fine. It is not a missing texture issue I thought it could be a memory issue however I disabled everything else but motorcyclehelmet.obj from viewport as well as render the issue still persisted.

PS. This may be a duplicate thread since I found similar issue with Fix blender/blender#64363 but I do not know how to apply this fix to released versions of blender also I have been unable to find a version where this fix was applied since I also tried 2.83.9 version but still same problem.
rc.blend11.blend
Exact steps for others to reproduce the error
Based on the default startup or an attached .blend file (as simple as possible).

This is not a bug. It comes from the “Pro Lighting: Skies.001” node in the world shading nodes. It is used as background emission, but it is missing a texture and emits in magenta.
Since the helmet is the only specular object in the scene, it is the only one reflecting the environment in rendered view. You can delete the Pro Lighting node, fix it by finding the missing texture, or use an emission colour for the helmet, as you’ve done everywhere else. If you really want to use the Principled BSDF, you must fix the world node tree.

Also, normally .blend files can be simplified by removing most objects and disabling settings, until the problem reveals itself more clearly. A 155MB blend file is not really simplified enough for a bug report.
