When checking the tasks your computer has been working on lately I found Gamma-Ray Pulsar Binary Search #1 has been run on your GPU and Gamma-ray pulsar search #5 has been run on your CPU.
Of those only FGRP5 has a graphical application and thus a screensaver to show. The 2 tasks that's available in the task list have both failed and the rest are GPU tasks that don't show any graphics and thus don't have a screen saver.
To get the screen saver working you need to run CPU tasks (Gamma-ray pulsar search #5 or Continuous Gravitational Wave search O2 All-Sky). Check your project preferences to select them and then check that they actually run and complete. Both of the Gamma-ray pulsar search #5 tasks showing in the database have failed to complete on your computer.
