Steps to reproduce

import {getCurrentInstance,defineComponent} from "vue"

const mapFilterChildCpt = (data,cptName,resArr=[])=>{
data.forEach(itme=>{
if(itme.type.name==cptName){
resArr.push(itme)
}else if(itme.shapeFlag==16){
resArr=[...resArr,...mapFilterChildCpt(itme.children||[],cptName)]
}
})
return resArr
}

export default defineComponent({

setup(){
let solt = instance.slots.default
instance.slots.default = ()=>{
let child = solt()
return mapFilterChildCpt(child,'by-carousel-item',[])
}

}

}）

What is expected?

You can modify the default instance.slots.default To modify (filter) the specific components under the slot

What is actually happening?

[edison1105]

maybe close by #2717, its not release yet.

It's maybe what @edison1105 said but you shouldn't manually modify the slots in an instance.
Also you should read https://new-issue.vuejs.org/?repo=vuejs/vue#why-repro
