can someone tell me please how come those images are the same SL ?!?!? it's part of a sequence that most of it is corrupt. What could cause it ?

Could it be that the camera has accidentally been animated to move behind or into some glass. It looks like what you are seeing is pure caustics.

Any sss material in the scene?

the camera is always looking through air and there's no SSS since I know they may cause problems... maybe it's something technical?
