Libreoffice 5.4.4 doesn't run second time.

Libreoffice 5.4.4 on ubuntu 16.04 will run after boot and after deleting user profile in .config but even then will not run a second time (even deleting./config/libreofice/4 again).
It gives Program error. Sometimes it runs again with no explanation.
Tried: different kernels, remove gtk2/gtk3, reinstall all package, disable java, change icon theme, run as root, using --safe-mode. No remaining related processes are running after closing.
