TypeError: Cannot read properties on undefined #688

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:

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