Trouble with VDataTable: TypeError: item.props is undefined

[capoaira]

I have a project which uses the v-data-table from labs (version 3.1.10). Now I need functions of the table which are not included in the labs, but in the last release (version 3.4.10). So I updated vuetify in the project, but now I'm getting the Error TypeError: item.props is undefined from other usages of the table.
Any Ideas how to fix that?

<template #item.created="{ item }">
  <p>
    {{ item.props.title.created?.split("T")[0] }}
  </p>
</template>

Maybe this question is related to #18784
