Error closing file for .mat file

Hi all, I’m trying to fetch the risk factor data from a database and then calculating scenarios on it. While trying to data, which is present as a struct I’m facing an error where it says Error ID: ‘MATLAB:save:errorClosingFile’. I tried changing the flag to ‘-v7.3’ (https://in.mathworks.com/matlabcentral/answers/18098-error-using-save-error-closing-file) but it takes a lot of space and time for the code to run. Is there any other way to fix this issue?

@Shashwat Is the file/database instance open in some other editor/software?

No, the connection to the DB and the instance is in MATLAB itself. It seems to be some issue with file size as when I try to save data for a smaller time period the .mat files are saved without any issues
