I'm facing the issue, that the Slideshow (Full Width) module on the top of the Home page does not show up, but instead of this I just see a large empty space. A headline module in the same section appears.

Trying to build the Slideshow module in a new section leads to a crash with Error message 'Object of class stdClass could not be converted to string'.

Website is https:///www.klassikyachts.de

I updated all SP modules, Page Builder Pro, Helix Ultimate Template and plugins, and Rental Template to the latest releases. I also cleared all caches, site and local browser.

The module and section are enabled, site cache is cleared.

Thanks for help
