Next.js 14 does not show pdf as static with next-auth

Environment

Next.js 14.0.1
next-auth Beta 5

Sql postgress on vercel

Reproduction URL

https://github.com/VittorioMorellini/dashboard

Describe the issue

Whan I try to show the static asset (Resume.pdf) If I am logged in, the program opens a new tab on the home page.
It does not show the static asset pdf, my resume.

It seems a problem of next-auth Beta version

How to reproduce

https://dashboard-vittoriomorellini.vercel.app/dashboard/resume

Go to this link and click to: "Download resume", it is a Link next to a static pdf file.
It should open a new tab with the pdf. It works if I am not logged in:

https://dashboard-vittoriomorellini.vercel.app

But if I am logged in it does not work; it does not open the static asset (pdf file)

Expected behavior

It should open a new tab in the browser to show the PDF file and you can download it from the new Tab

Start by reproducing the behavior at the provided dashboard URL with and without a logged-in session, using the Next.js 14.0.1 and next-auth beta 5 environment described. Compare the "Download resume" link behavior for Resume.pdf; done means the PDF opens in a new browser tab for logged-in users as well as logged-out users.
