Safari web content 100% cpu macos 13.2.1

Hi, I have encountered a problem for 2 days when while using safari with a simple google card I hear the fans start at maximum, then I open the activity manager and see that safari was using 90/100% cpu.

Usually when I use safari with only one card the fans don't even start.

I've already tried resetting the PRAM but to no avail.

The device in question is a macbook air 2019 with dual core i5, 8gb of ram and 128gb of ssd.

No programs have been downloaded lately except from the apple app store and I'm sure the mac is virus free.

Could anyone tell me how to fix it?
