after updating it today the Idea didn't start. downloaded whole gzip, removed .IntelliJIdea2019.3, still doesn't start. Splash screen appears and then nothing happens. The console like

that's with -Didea.debugger.trace=ALL - still nothing is logged, .IntelliJIdea2020 folder is not created.
The idea-IU-193.6911.18 starts and works ok.
is there something but idea.debugger.trace to tweak to get more logging?
