Lightroom Classic 8.4.1 not syncing

Lightroom Classic 8.4 on macOS 10.14.6 was sitting on over 6,000 images to sync and not going anywhere. Worked with adobe support connected to my computer twice and they could not fix, tried to say it was missing images. I tried the 8.4.1 update, still wouldn't sync.

Reinstalled Lightroom Classic 8.3.1 and it is syncing again. There is definitely an issue with 8.4
