Hi!
Fresh install,
On a Mac with Node.
The same thing happens to me with Node 22 and 20 and I guess with others too.

I installed with: npx nuxi init -t github:nuxt-ui-pro/dashboard
Then... pnpm run dev

I log in to localhost:3000
For example, I go to the "inbox" page and make an important change in the js code, for example on line 28 we have

const filteredMails = computed(() => {
    if (selectedTab.value === 1) {
        return mails.value.filter(mail => !!mail.unread)
    }

I change the ===1 to ===100

then... cmd + s to save and....

If I look at the browser console I find the blessed: Uncaught (in promise) TypeError: Cannot read properties of null (reading 'parentNode')

I made this reproduction of the error because I have been suffering from it, in a complex project in which I'm working, and I was actually suspecting that it might have been some external module of the many that I installed, so I resorted to a fresh installation and found out that the same thing is happening.

I would appreciate any comment, since this takes up a lot of time in my workflow, since it reloads the entire page with each cmd + s.

Greetings from Argentina.
