AMP error: Call to a member function hasAttribute() on null (0) [Error]

[diabitogoaway]

hello there, I've installed AMP plugin on my WordPress website but got the error below:
Call to a member function hasAttribute() on null (0) [Error]

Also the template mode is on standard in AMP settings

These are the things I've tried:
I changed the theme to default WordPress themes
I deactivated all of other plugins
I updated the WordPress core to version: 6.4.3
All of my plugins are updated
None of them worked

I use the karaous theme
And this is my website:
amatacompany.com
