Sequencer has become unresponsive and refuses to play back

All of a sudden I’m stuck without being able to do any of the following:

  • Edit my sequence contents’ movement
  • Play the sequence through the Play button
  • See the numerical values of items as they exist on the x, y, z planes

I am able to scrub through the scene and see how it plays out.

This occurred right after adding a FKControlRig transform for one of my newly added actors.

Admittedly, I’ve got a lot of meshes in my scene with maybe six, thus far, moving about. With more planned ahead.

My system’s powerful enough and I’m still stuck with this even after rebooting and having nothing else active on my PC except UE.

Any suggestions?
