Describe the bug

After upgrading Nuxt from v3.10.3 to v3.11.1 I get this error when I try to show the application from a Safari browser with a version <= 16.3.

For reproduce the issue I started from the Nuxt 3 base template (who is working) and I added a simple page.

It seems like some regular expression aren't supported in this browser version (as you can read HERE)

Safari v15.5:

Safari v17.3:

I think the following information could be usefull.

Quick edit: Just tested on a older version of Safari. And the problem is this:
new RegExp("(?<!\/)\/(?!\/)");

@Rizzato95 @hankdetank try updating ufo to the latest (1.5.2) by refreshing the lockfile as there has been a hotfix. But as nuxt is using the function for public paths (

nuxt/packages/nuxt/src/core/templates.ts

Line 330 in 6f2e7a8

'import { joinRelativeURL as joinURL } from \'ufo\'',

) it might not fix it.

Browser compatibility with ufo.joinRelativeURL is increased in ufo@1.5.3 (via unjs/ufo#228).

Please make sure to update the lock file manually (or using npx nuxi upgrade --force), remove node_modules if the issue exists, and check pnpm why ufo or npm why ufo to see why an older version of ufo might have been stalled.
