Adsense ads do not appear on Desktop, but run normally on mobile

Adsense ads do not appear in “In My Article Content” on desktop. But, all ads appear in articles for mobile.

Experiments I did:

1. I have turned off litespeed & paused cloudflare.
   Result: Ads still don’t appear on the Desktop (except ads that I inserted directly using my theme).
2. Delete cache and use another browser
   Result: ads still do not appear “in my articles” that I have entered using the adinserter plugin.
3. I inserted advertisements through the website theme.
   The result: ads appeared at the top and after my articles. For in articles it sometimes appears. but for the Adinserter ad “in my article” it doesn’t appear at all.

My question: Why do all the ads only appear on the mobile version but not on the desktop?

Addition:

1. I saw a report from Google AdSense that ads on “Desktop” devices for 1 month had very few impressions.
2. I didn’t activate the settings in the “Devices” menu. Just enable the “Posts” & “Shortcode” settings.
3. Ignore ads “above and below the article” and “float, vignette and anchor”
4. I have activated “Remote Debugging” but now still activate the cache plugin.
5. I don’t use any adblock in the browser

Cache plugins and more:

• Litespeed
• Cloudflare

Note: I know that google ads appear depending on the quality of the content. However, in this case the ads do not appear at all in “in my article content” on desktop but all appear on mobile.

Can you help me understand what is wrong here?.
Thank You.
