Lightroom Classic Very Slow to Sync

I saw another discussion about this, along with several non-Adobe pages, but can't make any progress. 

I am currently working with 35 images in my All Synced Photographs folder. I keep it as empty as possible, only adding the photos I need to work on. They are RAW, each image around 25MB in size. Nothing crazy. I use Lightroom on my desktop, laptop, tablet, and phone. I've had the same workflow and setup for a while, and haven't encountered this amount of slowness before. Even when there were a lot more than 35 images in the folder. 

The issue, syncing changes takes either a VERY long time, I'm talking upwards of 20 minutes for 1 image, or doesn't ever update/finish syncing. I have even removed all images from the synced folder and just had 1 image in there, which did the same thing.

Some info that might help:

- While it's syncing, there are no errors, it just says "Metadata" under the Sync Details/Errors section.

- Internet speed: 450Mbps down, 55Mbps up, with a ping of ~13ms

- Running Windows 11 Home

- I have plenty of hard drive space on all devices, 400GB free on my desktop as once example

- I did the "Optimize Catalog" process

-  I disabled Sync Smart Previews

- I added Adobe as an exception to my firewall

- I re-installed Lightroom

- I renamed the "Sync Data" folder, making it recreate 

- When I go to my https://lightroom.adobe.com/libraries, the data syncs there much faster, but doesn't get retrieved by whatever device I'm on

- I enabled "Specify location for Lightroom's Synced images"

I can't remembef if I've tried anything else, but none of the above made any difference. Hoping someone out there has some kind of answer.
