I uninstall 3.4.x and install 3.5.4. Runing first time on user i see splash-screen and LO closes. Runing second time works ok. The same problem on each user.
On one machine LO crahes, and did't want to work until I delete "application data/libreoffice" folder. Than we have same procedure, run first time close and run secon time than working ...
Thanks for your report.
