Repository: storybook
Issue: SB 6.4.19 - TypeError: render is undefined - after sb upgrade
Labels: bug,needs triage

**Describe the bug**
After following the guide at [https://storybook.js.org/docs/vue/configure/upgrading](https://storybook.js.org/docs/vue/configure/upgrading) and manually upgrading some other dependencies, a runtime error occurs when the webview is loaded. Impact: the SB frame and widgets are there, but no story can be loaded. The error occurs both on production & dev builds. I tried tracking the error in the source code, but it is too cryptic without knowing most or all of it.

```

**To Reproduce**
Due to the repo being private & the cause of the issue unknown, the only thing I could say to reproduce it is to upgrade a Storybook from 6.0 to 6.4.19. I've followed all the directions at https://github.com/storybookjs/storybook/blob/next/MIGRATION.md, tweaked various params but to no avail. The error persists.
