Hello !
Thanks helping for our problem. I solve mine finding the solution in an other thread.
The problem occurred after installing libasound2, the Alsa driver crashed Unity Editor, discovering that with `gdb`.
So I removed libasound2: `sudo apt-get remove --auto-remove libasound2` and had to reinstall Gnome: `sudo apt install gnome-session gdm3`
