How to fix "Ad blocker detected; please disable it to set up AdSense."

I'm trying to add Adsense to my blog, but for some reason, I receive an error under AdSense. Ad blocker detected; please disable it to set up AdSense.

I tried to remove AdSense and enable it under incognito. Also I added code in header

<script>
(adsbygoogle = window.adsbygoogle || []).push({
google_ad_client: "ca-pub-999999999",
enable_page_level_ads: true,
tag_partner: "site_kit"
});
</script>
