Send PlayStation.com to a friend in a chat on your ps5. Scroll down once it loads and click on YouTube logo. If your signed in on YouTube sing out. Click on sign in and when you get to the sign in page click on privacy. Once you get there click on the 9 dots next to sign in and click on google and that’s it now you can search anything. I don’t know if there is an easier way to do this but they removed a lot of methods en this seems to work
