LM5069: Noise always interferes with the LM5069, causing a sudden shutdown

Dear friends,

           Since the PCB board has no layout space, the output capacitance is reduced to 100NF.In the process of use, the output is often interrupted and automatically shut off.

           I want to parallel 100NF capacitor in GS of MOS tube to filter out interference . Is it feasible?

           This is my schematic.
