A client provided me with an .obj file (incl. tex folder and .mtl) but when I’m trying to import it either nothing happens or I’m getting an error message. (see below)
Anyone any ideas?

,
did you tried any other 3D-viewer or something? You may wanna try something like MeshLab to investigate this further. The error message seems not to be very usefull…
(And you also know that obj is a text file? So you can look into it…)
