Nuxt: useHead undefined after initiating a regex (since monday)

Environment

Linux (this problem doesnt appear to happen on windows). tested on different node versions.

Reproduction

https://stackblitz.com/edit/github-819pq2-4sknkq?file=layouts%2Fdefault.vue

Describe the bug

"var emailregexx = /^[a-zA-Z0-9.!#$%&'+/=?^_`{|}~-]+@[a-zA-Z0-9-]+(?:.[a-zA-Z0-9-]+)$/; useHead({ meta: [ { name: 'viewport', content: 'width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0', }, ], });"

This code crashes. And my question is why. I've created an issue on nuxt at: https://github.com/nuxt/nuxt/issues/27392 . There danielroe asked me to created to ticket here.

It happens since monday(maybe friday or thursday) and this code is already years old.

When you remove the regex line, all works normally again.

When you change the regex to the following 2 options it works: /^[a-zA-Z0-9.!#$%&'+/?{|}~-]+@[a-zA-Z0-9-]+(?:.[a-zA-Z0-9-]+)$/; (removed the `)

/^[a-zA-Z0-9.!#$%&'+\/?`{|}~-]+@[a-zA-Z0-9-]+(?:.[a-zA-Z0-9-]+)$/; (escaped the /)
