Do you have the same problem with an OBJ that has no textures? This looks like it could be related to texture files. Can you post the obj/mtl any texture files that are used? Since we can’t duplicate this here with our own files we’ll need to see what’s different abut yours.
On our end, these OBJ files are generated out of Metashape. We process hundreds of these a month so streamlining the process from Metashape to a scaled/oriented object. With the MTL file in the folder, users are able to open the obj file and the texture file is automatically associated. When we use only the JPG, the user needs to drag/drop the file.
I have not gotten a crash report. It cycles through these lines in the command prompt without crashing. I end the task through task manager. I do realize it takes a bunch of ram up during its hate cycle.
