Crash Occurs When Simulating in Editor and Copying Camera Key in One Sequence Then Opening a Second Sequence

-When opening a sequence while simulating in editor and copying a key and changing sequences leads to a crash
-Does not proved callstack - but one is available in the UDN link (See SequencerCrashB)
-Crashes in Main just switching between sequences while simulating

1. Open attached project
2. Simulate in editor
3. Open Sequence_A
4. Open Sequence_B
5. Notice alternating between these does not cause a crash
6. In Sequence_A copy a one of the keys
7. Open Sequence_B
8. Observe crash

Expected: Copying a key in sequencer while simulating in editor and then opening a different sequence does not lead to a crash

Results: Copying a key in sequencer while simulating in editor and then opening a different sequence leads to a crash
