Bad version or endian-key

I have a application built in Matlab which I deploy using the Builder-Ex toolbox. Inside the application I am saving some objects of user defined classes (using the 'save' command) and later load them (using the 'load' command). In order to load the objects properly inside the deployed application, I am using the %#function directive. However, intermittently the application throws an error in the deployed mode with the error message being "Bad version or endian-key". The error identifier is 'MATLAB:Deserialize'. Also note that I am NOT using parallel computing in any way.

Could anyone help me in resolving the problem?
