Can't switch off YouTube dark mode

Question

I can't switch off YouTube dark mode; the image here explains it:

Can someone help? Restarting the browser doesn't help. If I switch mode and restart it, it is dark again.

Answer 1

• go to chrome://extensions/ and check for extensions that may be forcing dark mode preference
• then press CTRL + SHIFT + DELETE and delete cookies which may store the dark mode preference because you are not loged in into YouTube
