Hello, thanks for your reply

these files weren't empty, but they don't show my setup (remoted from PI4 in garden),
now it runs fine, I'd to reconfigure and check after new install (astrometry was not lost/trashed ), i don't know who are the configs files while some datas weren't lost... but some away or incomplete ?!

I think, it seems, that was maybe a problem with files/folder rights... as no access to xml or other ... I don't know, the difference after the new install: I was only able to reconfigure and edit/save new profiles (not possible after crash, saving new profile/config led to crash).
I've tested it before clouds came, no problem

I think, in my case, that the problem was in folder /home/name/.local/share/kstars
i've not found the xml with "profiles" (disapeared in ekos before the crash), but there is "userdb.sqlite"

I've had this problem only on PC, the PI4 works fine (indiserver + kstars sometimes for polar align...)
