An error about UE5.4 animation redirection, opening the redirected animation UE crash problem

When I redirected the animation of the Countess of Unreal Tournament to the Metal Man, UE crashed when I opened the redirected animation. I also tried mixamo's model, and redirected the old UE4 model to the mixamo model and there was also this problem. Although it crashed when opened, I can use this animation resource normally in the game. Has anyone solved this problem? I am a UE novice, please bear with me.
