All Saved Passwords gone on several/all devices

I noticed my passwords have disappeared from my devices. I have sync set up across a few devices, and was made aware of the issue by my phone not suggesting a password I knew was saved. I saw sync for passwords was set to off, which was not my usual setup, so I set it on and then looked on my laptop to see if the passwords were saved there, and they were not.
I would rather not rebuild them all as some passwords were only saved in my brave sync chain and not other browsers I use, and if possible I’d like to retrieve them from another device in the sync chain?
