Bug with the sss in Cycles Blender 3.1.2 rendering

Hello, I think I have a bug with the sss in Cycles rendering, I have strange artifacts like the appearance of bands as soon as I activate the sss in cycles. In eevee it seems to work.
As soon as I desactivate the sss, everything is ok.

This happens with version 3.1.2 of blender.
Also with version 3.0 but with version 2.93.5 it’s ok.

I tried to export the object in obj for cleaning it but nothing worked.

The SSS mask and the textures are from SubstancePainter.

If you can tell me if it’s a bug or if there’s a new way to use sss, that’ll be fine.

I am attaching the files to show you the problem.

Thanking you in advance.

Best Regards
