Firefox Sync data not showing up on new laptop but still available on Firefox Android on my phone

Hi, I've tried finding the solution online but I can't. My old computer broke a while ago but all my data on Sync was backup up, and I've been accessing it from my Android phone and other laptops just fine. I just got a new laptop and wanted to sign into Sync to get all my data on here. However, even after syncing, nothing is showing up (bookmarks, saved passwords, etc.). It's all still on my phone though, under "Desktop Bookmarks". Also my phone is currently disconnected from my Sync account because I changed the password to it and haven't logged back in yet. I'm scared that now if I log back in, I will lose everything because it will Sync and take the new data from this computer, which is nothing. Thank you for your help!
