Error information of RC=2

Dear FLUKA experts,
When I try to run a flair with the CT after adding a noise, the error of RC=2 occuring. But I have runned the flair with the same CT without adding a noise, it can run without error.
The information are shown as follow.

I can provide a CT privately if needed!
