1. Open the attached project and open its master sequence
2. In property of the even track key, set a static mesh
3. Check the property of the key again
4. If step 3 did not crash, create a new key, specify the user defined structure, and set a static mesh. Then try to check the property of the key.
Expected result: No crash and static mesh reference will be preserved when checking the property again.
