Where can I find this plugin option? I am also having a conflict and I cant find it.

I think you misunderstood. My profile had special characters “,” and “.” in my profile name and list names. Remove any special characters from these places. Do not add “Inc”.

I had the same issue. After setting Allow Duplicate sign ups in the Mailchimp integration set up, the error changed to “Something went wrong. Please try again”.

I kept thinking about what could be blocking the sign ups and then it hit me, my Mailchimp account name and lists had special characters. Particularly in my case, I had “, Inc.” at the end of my company name. Once I removed this, all my sign ups started working again. I hope this helps you.
