Groups plugin prevents editing any page/template in Elementor

We use both the ‘Groups for Woocommerce‘ and the free ‘Groups‘ plugins for selling educational course memberships on our site.

Unfortunately since recently, the free Groups plugin is stopping us from editing anything in Elementor / Elementor Pro. When trying to open any template or any page created with Elementor, we are seeing a fatal error (see below).

We have traced the issue back to the free Groups plugin by deactivating all plugins and activating them again one by one. When we deactivate the free Groups plugin the error disappears and we are allowed to edit in Elementor again. The Groups for Woocommerce plugin is not giving any problems though. It seems the free Groups plugin is somehow blocking editing in Elementor as the error states that access is denied. We have looked at the Groups plugin’s settings, but can’t immediately find a setting that remedies this issue.

Below you can see the fatal error that is shown with the WordPress debug function active:

There has been a critical error on this website. Please check your site admin email inbox for instructions.

(P.S. we have altered some subdomain and folder parts of the urls in the error for privacy reasons)

Thanks for your help in advance.

Kind regards,
