Connecting newly installed Patreon Wordpress plugin to Patreon - There has been a critical error on this website

WP 6.6.2 with PHP 8.1.22
Patreon WordPress 1.9.1 with API v2

Hi, I’ve installed the Patreon Wordpress plugin into my EasyWP site and when I try to connect to my Patreon with the OAuth prompt which says

" Patreon Wordpress would like to…

  • •Create an OAuth client for your campaign"

I get this error : “There has been a critical error on this website.”

All other plugins have been deactivated. I’m a noob at this sort of thing so any help would be appreciated, I can follow instructions ok I am ok with things like this once instructed.

It means that some error happend at your website. You should check your site’s error logs. Or you can create a support ticket with your host and ask them if you dont know how to do it yet.
