In R2019a, it seems that selecting "Log data to workspace" of the Scope block does not actually log the data to the MATLAB workspace as in old releases.

I have also tried using the To Workspace block and the behavior is the same. What setting has been changed in R2019a?

This behavior is expected in R2019a.

Starting from R2019a, the default setting of "Single simulation output" option has been changed from 'off' to 'on':

Therefore, Simulink returns all simulation outputs to MATLAB within a single SimulationOutput object, which include signal, state, output, DSM logging, and scope and toworkspace block logging. If not specified, the variable is named as out.

To get the outputs in separate variables as before, you need to uncheck this option.
