I finally found the spam origin.
In my case, it was from Opera Cashback.
Spam stops when disable it.

Hi!

I'm having spam logs in the console in dev tools on Opera Gx.
The same thing happens on two different machines.
I already disabled all extensions, re-install, and nothing changes.
Can someone help me?
