Thx, finally it worked (idk how?) but i have the same problem with the same model that i just changed a little bit
here's a wetransfer link: https://we.tl/t-cjBbybOhbZ
I'm new in Substance Painter and in the 3D in general so i surely made a lot of mistakes (exporting highpoly with too much polygons...) that may why it won't work.
Thx, i waiting for your reply.

I couldn't get your low poly version to even load properly.
I was able to load in your high poly version into Blender, and your major issue is that you're using way too many polygons.
This object:
Has a whopping 10,698,752 faces!!! (21 million tris) That's way too heavy and all the detail you put into the model could be done with under 20,000 and even less! I've worked on very high end models for games, and sometimes I'll hit a few million for the highs on complex organic models with various parts, but never 10 million for weapon objects.
One rule of thumb is you never increase your poly count unless you've fully utilized the current count. This will come with time, and I would suggest you make it a goal when sculpting and modeling to do the best quality at the lowest count possible. Activity do what you can to never increase polygons unless you have to.
