Update 1.51.110 lost my data in two systems with Linux

[PassWoRD]

Hi,
like too much people Brave also lost my data
in two different systems,
in two different modality,
in two different timings.
I have a laptop and a pc that I use simultaneously during all days with s.o.
Kubuntu 20.04 update (5.15.0-71-generic kernel)
KDE Plasma Version: 5.18.8
KDE Frameworks Version: 5.68.0
and
Brave browser update 1.51.110 (from 1.50.125)
no Sync

Two days ago I discover all my saved passwords lost in the laptop, I start watch community.brave.com without a valid solution.
Disappointed to discover the lack of your solution, I decide to export the saved password from pc to laptop to buffer the problem ( I use the system in different time, so not all data are saved in both)
Yesterday at the end of the day, I discover that my pc lost passwords and bookmarks (!!), so I hasten to export bookmarks from laptop.
Today my laptop has not yet lost bookmarks…

I did not change passwords
I did not copy the profile from another machine
I don’t use any sync feature all are saved in my local files on pc

@PassWoRD I see you commented over at NOTICE: Unexplained Data Loss Issue - #29 by clifton and hopefully will be resolved with that. We’ll keep this open, but please make sure to mark a solution here if you see it does get fixed with newer version as it comes.
