iMessage syncing paused on MacOS

I have multiple Apple devices: an iPhone 15 Pro Max, iPad mini, iPad Pro, MacBook Air and MacBook Pro all of which are running iOS 17 public beta software 3 for iOS/iPad OS, and the Macs too are running public beta software 3 of macOS Sonoma. For some reason, all of my devices but 1 (the MacBook Pro) isn't syncing my messages. I've tried signing out of iMessages of my MBP. I then tried to disable iMessage syncing just on my MBP, which didn't work, and I was brave enough to just disable the syncing on ALL my devices, for the sake of losing them, and yet it still says "syncing paused." I don't know if I have to sign out of my AppleID all together on my MBP? That's my last resort. I don't know what else to do. At first I thought maybe it's because I'm running beta software, but why is my MacBook Air fine?
