[BUG-REPORT] Possibly false error message in level sequencer

Error:

The following message is displayed when using the ‘quick bind’ function:

Steps to reproduce:

  1. Create or Open a level sequence
  2. Ensure the sequence blueprint window is CLOSED
  3. Add an Event track if it doesn’t already have one
  4. Add a new keyframe to the event track
  5. Select the keyframe and use the ‘quick bind’ dropdown option to bind anything to it
  6. Message shown above is displayed

NOTE: Message is NOT displayed if the level sequence blueprint window is already open (including minimized)
Regardless of the message being displayed, the required nodes ARE added successfully to the blueprint.

I have tested this in 5.3 and 5.5.4 - the results are the same
