Error with CVX"Struct contents reference from a non-struct array object"

Hello,
I am running my program on Matlab. My program uses CVX for optimization. Now when I run the program it gives me the following error:

Struct contents reference from a non-struct array object.

Error in cvx_global (line 76)
osolvers = cvx___.solvers.list;
I am struggling hard to resolve it but no progress.
