White page on requests with Sec-Fetch-Site: cross-site

I have problem loading pages in WP after last update.

when i click a link to my website (eg coming from google) I see only a white page,
if i digit the url in the address bar I see the expected page.

Looking at the browser requests in the first case I have two rows more:

Sec-Fetch-Site: cross-site
Referer: https://google.com/

Note that I tryed to disable all the plugins and change theme: nothing change.
Morover on the same server I have another instance of WP (same version) that does not have any problem.

PS: WP_DEBUG does not give me any information.

Any suggestion?
