我自己找到原因了，我这边的原因是你场景中有个对象加载了一个龙骨，这个龙骨是你在bundle里的，而这个bundle你是异步加载导致的，你可以先将这个对象的龙骨文件绑定删掉就不闪退了

不行貌似只要原始对象有龙骨了然后再做替换就会报错
this.armatureDisplay.dragonAsset = ret.dragonAsset;
this.armatureDisplay.dragonAtlasAsset = ret.dragonAtlasAsset;

问题解决了
正确替换龙骨的步骤应该是：

let armatureDisplay = node.getComponent(dragonBones.ArmatureDisplay);
let ret = loadBones(boneName)//忽略加载龙骨过程
node.removeComponent(armatureDisplay);//移除原来的龙骨组件
armatureDisplay = node.addComponent(dragonBones.ArmatureDisplay);添加一个新的龙骨组件
// 替换龙骨资源
armatureDisplay.dragonAsset = ret.dragonAsset;
armatureDisplay.dragonAtlasAsset = ret.dragonAtlasAsset;
armatureDisplay.armatureName=armatureName;
