Endless error messages with Site Kit

Does not matter what I do trying to activate site kit, I get endless errors, so I’ve deactivated it and deleted it. Resetting Site Kit does nothing, I just get an error message. I would still like to use it. Perhaps someone can explain these errors to me: Invalid client ID. If the account I’m using to sign into WordPress is not the one that was used when the Site Kit plugin was installed, how wold I find out that client ID? Also, the error “The request to the authentication proxy has failed with an error: invalid ‘site_id’ or ‘site_secret’” The help explanation is also beyond my understanding. In laymans’ terms, any suggestions? Thank you in advance. https://imgur.com/a/7LRr04m
