You may not remove the cookies properly. Try to install a plugins called Cookie AutoDelet for your browser.

Plz take a look: https://stackoverflow.com/questions/179355/clearing-all-cookies-with-javascript you have to create a loop to remove the cookies using JS, otherwise you need to remove them one by one – HamiD Sep 06 '22 at 13:08
Looks like YouTube's using cookies - but when I remove it, the cookie restore. – AlignItems Sep 07 '22 at 12:49
