Termius loses settings

I’ve made a clean installation last month with KDE plasma, I installed Termius SSH, but very often days or weeks, all settings are gone or asked me to delete settings because they are corrupted
I use Termius, on other Manjaro KDE without any problems. I tried to uninstall/install after deleting config directory, but the problem persists
Any ideas?

Filesystem gone bonkers? If using btrfs it can get confused if there is a lof of changes very quickly - the same files removed then added then removed again repeatedly.

Buti it is just ideas …
