TypeError: Cannot read properties on undefined

Vue devtools 7.6.3

When vite hot reloads a page, using the 'select component on page' causes the following errors to occur. This can be fixed by reloading the page.

This was not the case before on 6.x.x

We mainly use:

• Vue 3.5.12
• Vite 5.4.9
• Pinia 2.2.4
• Typescript 5.6.3

If you need additional info on packages, the issue or anything else, feel free to ask.

It also somehow happened for me. I don't know how to reproduce it, I just saw it in the console after a while.

Screenshots

It seems like the error leads here:

devtools/packages/devtools-kit/src/core/component/state/process.ts

Line 66 in 0cf7f09

for (const key in instance.props) {

It should not happen in most general cases, so we need a sample to avoid this error. Can anyone help us? Thank you
