LTM4625 Output Noise

Hi team

Two LTM4625s were designed as the circuit attached.
The same circuit was used to apply to two models.
I made the artwork as below.
The circuit with the GND on the 1-Layer produces noise.
The total number of floors is about 70 layers. 70-layer (about 10-layer GND) There is a GND in between.

Can you tell me what the problem is?
Is there anything you shouldn't do on the Artwork?
