GFX obj file saving as paint 3d

I am trying to learn how to make simple renders, however when I watched a tutorial, and every tutorial I watch, the texture or the hats don’t work.

For some reason it saves the texture as a paint 3d file???

Does anyone know how to fix this?

This is because u have set paint 3d as default app for all 3d models. Right click it and open with blender

right click on the .obj, click “Open With” then find blender. then tick the box that says “always open with this program”

It still is not working with paint rig V3
