Open a new MATLAB session and work in that. For example on Mac you would right-click on the MATLAB icon in the dock and select "Open Additional Instance of MATLAB"

If you needed access to the workspace of what had gone before in the session, then you would not be able to get to that, not unless you had managed to save() what you needed.
