Cura 5.6.0. does not start on SteamOS

[Knochi]

From one day to the other stopped working... not sure if an update of cura or system was installed in the meantime I did some python stuff in between but used virtualenvironments.. so don't think thats the reason.. and well.. it's a flatpak right?

Your logs look normal. Maybe try to delete the cache: rm -r ~/.var/app/com.ultimaker.cura/cache/

Ok, so this error messages are normal??

I reinstalled Cura and it’s running again. So I guess deleting the cache file could have worked as well.
