Are you double clicking in the "Current Folder" display within the Matlab window or are you double clicking on the file in a normal windows File Explorer window?

To fix the issue of .m files opening in new MATLAB windows, try setting MATLAB as the default program for .m files on your computer and ensure it's correctly associated. If that doesn't work, consider resetting MATLAB's preferences or reinstalling MATLAB. Opening files from within MATLAB's own interface might also help.
