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’)
