Lightroom Classic not syncing one collection

I have read every single post with every possible piece of advice for how to fix the issue and nothing has worked so I'm posting mostly to see if I can get some assistance from someone at Adobe. I have ONE collection in my LR Classic catalog that will not sync. I did all the edits on my iPad and they synced perfectly fine to the cloud because I can see the files w/ all the most recent edits when I go to lightroom.adobe.com but for whatever reason, the files will NOT sync to LR Classic, so I am unable to export these files at full resolution for my clients. Every other edit that I have done outside of these photos is syncing perfectly fine. I have tried moving that collection, renaming it, forcing the sync, performing small adjustments on the photos, etc - and nothing will prompt the edits I performed on my iPad to show up. But files that I am currently editing are syncing fine. I do not have the time to re-edit 250+ photos and my client cannot continue to wait. I used Lightroom CC (which is syncing fine) to export JPGs of the edited photos w/ the smart preview so that my client could at least have something web sized to share but they are 1.3MB files that my client definitely cannot use for printing purposes. I pay $52/month to not be able to do something as simple as sync my files and I'm losing my mind, someone at Adobe please help. I'm on Monterey 12.4 and cannot upgrade higher because other apps I use will not work with newer versions. My LR Classic version is 12.0.1 Camera RAW 15.0. If I tap on the cloud icon in the top right it tells me that there are 7 files syncing under "Local Activity" but no files come up when I search for sync errors so i don't know which 7 files it thinks are stuck.
