Steps to reproduce

I use a wrapper component for router-view
and everything is ok in dev mode, but got error after build and deploy to product server:

index-D_lnheNN.js:14 TypeError: Cannot read properties of null (reading '0')

function Ga(e) { if (!Eo(e)) return e; const {shapeFlag: t, children: l} = e; if (t & 16) return l[0]; if (t & 32 && He(l.default)) return l.default() 

 <router-view v-slot="{ Component, route }"> <transition name="fade" mode="out-in"> <KeepAlive :include="include"> <component :is="wrap(route.fullPath, Component)" :key="route.fullPath" /> </KeepAlive> </transition> </router-view> 

and it's fine after I downgrade to 3..4.23

What is expected?

no error in both dev and product mode

What is actually happening?

TypeError: Cannot read properties of null (reading '0')
