‘The content’ fail

When i try to edit my checkout page with elementor it fails. I get the message, that i have to get the ‘the content’ funktion. I have tried to deactivate all the plugins and found out that it was because of the woocommerce plugin. When i deactivate woocommerce i can edit the page. How do i fix this?
I hope someone can help me, i am very new to using wordpress and creating websites. PLEASE help me.
