Failed to run method

I am recording a method, then run that method to a similar file. The method is like this:

model.result("pg39").run();

model.result().dataset("dset1").createDeformedConfig("deform1", "mesh2");

model.component("comp1").geom("deform1").export("D:\matlab\y1file.mphbin");

when I run it, I got this error message:

Failed to run method.

Failed to create file. - File: D:\matlab\y1file.mphbin

It seems it failed to save the geometry as a file. Could anybody point out what should I do to solve this? Thank you.

Update: this is already solved. I just unset the"enforce seurity restrictions" in preferences. I cannot delete this question from this forum.
