Bake mesh maps not displaying/doing anything

Hi, I've made a low and high-poly version of a model. I'm trying to bake the detail onto the low poly model, but when baking in Substance nothing changes on the model and it stays the same. I've been trying to resolve this for hours and have not found anyone with the same problem. I've attachde the .blend file below, would really appreciate some ideas or answers, thanks in advance!

Substance Painter version: 8.2.0, (same problem in older version).
Blender version: 3.3.1
Platform: Windows 11 (22H2)
