Unreal Engine Issues and Bug Tracker (UE-47859)

Description

when change sequence struct param, the editor is carash.
It occurs in the case of using "Sound Wave", but the same problem occurs when "Sound Cue" is used.
Attach application log, and crash dump file.

Steps to Reproduce

1.Create New Structure at Content Browser.
2.Add SoundWave to member of Structure.
3.Open Level Sequence.
4.Add Event Track, and add new Key in anywhere.
5.Open the property, and set the structure created in "Parameter Structure".
6.When change SoundWave parameter (sequence struct member parameter), the editor crash.

Result:
Editor Carashes due to an assert.
Expected
Not crashed.
