Easy methods to scorching replace bundle challenge – Cocos Creator

Hello,
I’ve a sport with multi bundle inside(sport A), a begin scene(Major) loading each factor and present the corridor, then sub sport will likely be obtain. Every thing works completely, now i would like scorching replace type one other sport(sport B) to sport A however has troubles.
It can not scorching replace as a result of sport A construct with md5 possibility. So i create one other challenge(sport C) with a easy scene to load scene from sport A, and construct with no md5. Then i scorching replace sport C from sport B and it really works.

@ccclass
export default class GameC extends cc.Element {
    onLoad(): void {
        let url="https://myurl.com/distant/Recreation";
        cc.assetManager.loadBundle(url, { model: 'xxxxx' }, (err, bundle) => {
            if (err) {
                return;
            }
            bundle.loadScene("Major", (error: Error, scene: cc.SceneAsset) => {
                if (error) {
                    return;
                }
                cc.director.runScene(scene);
            });
        });
    }
}

However one other drawback, Major scene from sport A load one other bundle with no md5, an it fail
**Obtain file failed: path: belongings/framework/config.json.
So i have to cross possibility { model: ‘xxxxx’ } for all operate loadBundle in sport A or one thing else?
How am i able to resolve this?
