Substance painter constantly crashing at baking attempt

Good day everyone!

I'm a bit dissapointed, since I have to realize that we, SP users have to face great issues at baking specially due to 3D scan objects. 

 The issue:

- high poly mesh: 60 mill tri (clean mesh)

- low poly mesh 2mill tri (clean mesh)

- 9 UDIM (lets be honest, not a high number)

- normal bake goes true, but from AO the line dies. As soon as I try to bake anything but normal it crahes.

I'm quite losing the point of using SP if I can not manipulate in a procedural way my textures by using the baked out maps.

High to low is baked based on naming convention (_high _low) Since (side note) SP bakeer has some issues due to position attribute if I let it work based on relative to bounding box - also a big question mark, but at least it can be handled.

My pc spec: ryzen 5950x, 128 Gb RAM, RTX 3060 Ti (I know that is my WS's weak spot, but 9 udim and the mentioned meshes should not build a cap for this gpu)

All drivers fresh (nvidia studio) SP is also updatet to the latest version (7.4)
