Can SXG decrease revenue in Google AdSense?

Hi,
I recently connected Signed Exchanges to my website and noticed that my income in Google AdSense has decreased. I’m not sure if this is related to the SXG connection.
Can SXG affect revenue in Google AdSense? I read that some cookies may be lost when going to the site, could this be the reason?

There is more information about SXG: Improve site load times and SEO with one-click support for Signed Exchanges on Google Search
And the cite about Cookies:

  1. We also strip out headers that don’t make sense within the context of Signed Exchanges (like Connection, Keep-Alive, etc.) as well as security sensitive headers (Set-Cookie, Authentication-Info, etc.).
