My saved passwords from build in brave just disappeared

#1

I haven’t used my desktop ( iMac ) for 1 month being left out of town. Before I have left everything was just fine with brave. When I started using my desktop again, I realised that all my passwords vanished.
I did look in my “saved passwords” and there was none, only 3 web sites which I did block before to remember.
All being said I started to use my passwords from memory, brave offered to remember them, but unfortunately it doesn’t store them.
I reinstalled Brave and same issue. I did clear history, cache and so on…
Any ideea?
Thank you
