LO won't start on OS X Yosemite anymore (10.10.5)

I was using LO regularly, however, suddenly, it’s not starting anymore and it’s not able to open documents (writer), calc, presentations, nothing.

I tried reinstalling, previous versions, latest version, removing/updating JAVA, no results. Played with Gatekeeper settings, no effect. LibreOffice does not start, or it starts for fraction of a second and is terminated immediately.

Trying this distribution: LibreOffice_5.0.3_MacOS_x86-6
