error after updating to storybook 8

[pkyeck]

Hi,
I'm trying to update my storybook v7 installation to v8:

• ran the storybook migration
• updated the plugin to v5.0.0

but I'm seeing fn is not a function with the withRoundTrip.js:74:1 mentioned in the stack-trace

TypeError: fn is not a function

anyone else getting these errors after the update?
