Odd, I've tried making a static build of the exact sandbox this issue references I can't reproduce locally.

Debugging the code it seems related to the control panel, which dives into useArgs.
that hook throws with:

Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'type')

here:

storybook/code/lib/manager-api/src/index.tsx

Line 489 in 5658390

const args = data.type === 'story' ? data.args : {};

I'll open a PR making this more fault tolerant, even though I can't reproduce it locally...
