Hello @mmzkh
Thank you for the support topic, From the screenshot, it looks like you have overbudget CSS.
The AMP allows only 75Kb of CSS on a page, AMP plugin finds CSS that is being used on a page and optimizes it.
I will recommend checking the AMP validation tool to find out if one of your plugins or your theme causing CSS overbudget
Visit Admin Toolbar find the AMP->CSS option click on it. you will land on something like below tool, where you can find Plugin or theme causing overbudget CSS

Once you find root cause
Plugin: If one of the plugins is causing overbudget CSS, please contact that plugin author and ask them to optimize CSS, or choose an alternative Listed on our Site.
Theme: If your theme is causing the issues, switch to Reader Mode and Choose AMP-compatible themes such as Astra or Neve
Hope this helps!
