"Crash when using "Toggle watch pose" in any node of the animation blueprint. The crash happens when you save the ABP after enabling toggle watch pose and you reopen it."
1. Open the Lyra project.
2. Create an empty Animation Blueprint for the mannequin skeleton.
3. Open the ABP and add one "play" node for some animation sequence (e.g. MM_Rifle_Idle_Hipfire).
4. Connect the animation node to the output.
5. Right click the animation node and enable "Toggle watch pose".
6. Compile and save the animation blueprint.
7. Close the animation blueprint.
8. Reopen the animation blueprint.
Expected Results:
The animation blueprint opens without issue.
Actual Results:
The Editor crashes.
