Conflict with Generatepress theme

Hi,

This new plugin looks very promising, Contact 7 forms with use of Gutenberg blocks.

However, after activating it won’t work. Just the spinning logo.
I am using the Generatepress theme.

After switching from Generatepress – child theme to the Twenty Twenty-Three it works.

Looking in the debug it shows a PHP Fatal error, look at the trace at the end.
It looks like a conflict between plugin and theme.

Is this something the theme-builder should fix?

Kind regards,
Jan
