Weird artifacts in Substance Painter when exporting from Blender with Shade Smooth...

Hey everyone, i’m having what seems to be normal map artifacts when baking in Substance Painter after exporting from Blender. When I export with Shade Smooth, I get these strange edge artifacts, but when I export with Shade Flat, everything works fine.

• I’ve tried recalculating normals and applying transformations, but the problem persists when exporting with Shade Smooth.

• I tried pinching the edges but it just creates more and more artifacts.

• Substance Painter bake settings seem fine, but the artifacts only appear with Shade Smooth. It's like it's creating edges that aren't in my low poly topology.

Any advice on how to fix the issue with Shade Smooth while keeping the correct normal map in Substance Painter ?
