The user provided a video that shows how to reproduce the crash: [Link Removed]
1. Open the project located at: [Link Removed]
2. Open the BP_MOBA_MasterHero, BP_MOBA_MasterCharacter, and BP_MOBA_MasterMinion blueprints.
3. In Master Minion, select the character movement component and toggle the RVO Avoidance option on and off.
4. Compile the blueprint.
5. In MasterCharacer, toggle the RVO Avoidance option on and off.
6. Compile
7. In MasterHero, toggle the RVO Avoidance option off
Result: Editor crashes
Expected: No crash would occur
