Having a problem with Normal Baking a high poly model into a low poly model. (with file included) I'm having this issue where, yes i can bake the normal map, but when i apply it onto the lowpoly model with the normal map something weird happens in the middle of the model. I have no idea what to do.

And when i do put it into the model it looks like it has more blurry and less detail than the sculpted one even though the textures is 4k, but maybe thats just me.
I will put the file here. You can look and try for yourself. A detailed description of what i need to do would be highly appreciated!

I've tested with a 32 Bit Float image and it works fine:
