Oracle Reports Builder does not start

I cannot start Oracle Reports builder on my working machine. It is a Windows 10 64bit. Forms builder works ok. Reports builder used to work in the past, I did not use it for a while, and now, it does not launch.

When trying to open it, I can see the splash screen and the main window for a few seconds. Then everything closes. No error, no minimized window (I read about this issue, but it is not minimized, it seems to be closed). When I try to open it for a 2nd time, the splash screen just appears briefly, and nothing happens.
