Inability to see shared photo albums on my Mac Mini

Recently updated software to MacOS Sequoia 15.6.1 on my Mac Mini M1. I have 50 Shared Albums that can be seen on all other Apple platforms (iPhone, iPad, and MacBook Pro) + the iCloud. These albums are functional as I can add and remove photos from them on these other platforms with no issues. I have tried several of the most commonly recommended fixes to solve the issue, with no luck.
