Problems opening projects

I’m new to Unity3D and I installed it on my pc to try it out. Nothing special but as soon as I created my first project Unity closed.

I checked if the project was actually created, and I found the folder in the specified directory, so I reopened Unity and I found the project in the project list, i opened it and Unity closed again.

No error messages, no crash logs, nothing, just closed: in fact the system monitor shows that the process interrupts. I searched online and found a couple of non-working solutions, for what i think is my problem. To say some of them, the UnityLock file, even if removed, gets automatically re-created once i try to open the project and as I said the process stops so there aren’t any processes still going on to close. Rebooting also doesn’t work.
I tried to run it from the terminal, with this results:

When I open Unity:
Gtk-Message: 20:43:09.489: Failed to load module "canberra-gtk-module"

When I try to open a project and Unity crashes:
Errore di segmentazione (core dump creato) "Segmentation error (core dump created)"
