LT3964 LTspice reference circuit doesn't work

Hi, Support team

I'm simulating the LT3964 reference circuit in LTspice. Moreover, the same circuit is evaluated with the real ES board.

In LTspice, when the output capacitor(C3) is set from 2.2uF to 10uF, ALERT is asserted and it does not work.

With a real board this is not the case and it is working.

Why doesn't LTspice work? It doesn't seem to be the conditions under  ALERT asserting.
