venture theme header not showing on amp

From inspecting your theme it looks like it’s not fully AMP compatible. The visibility of the header can be resolved by adding the below to your themes style.css file however it seems you hamburger menu and search box may not work in AMP.

html[amp] header#masthead {
opacity: 1;
}

Have you considered trying out the plugins reader mode, while installing and activating a compatible theme for your AMP URLS? Note that by doing so you non AMP URLs will not be impacted.

Let me know if you have any questions on the above.
