I am stuck on Catalina on a 2013 iMac

Hi friends I am stuck on Catalina, wondering if there is a way in open core to rebuild so I can try to advance, my main issue is that the App Store will not work, so I am unable also to sign into the App Store/iCloud to try and see if I can restore logic on this computer.

Let me know if you have any solutions.
