Parainvite setup with Microsoft has locked me out of the administrator area of joomla?

Hi there, I am using parainvite on my easysocial and joomla site. I tried adding the Microsoft id and secret key and now I cannot access the backend of my joomla site. I keep getting this page here: https://cl.ly/3j1B300S3z27

I also tried the microsoft link on the frontend of my site and get this 404 error here: https://cl.ly/3j1B300S3z27

I also see you have a professional service to add all of these setups for me and I was wondering how much this costs as I would like all these setup and tested so as to make sure there are no errors like the ones I am experiencing now. Thank you in advance
