My opera browser crash after I start it for a few minute.
I find there is some error messages in the terminal:

The Gtk-warning messages can be ignored.

Tried running Opera with a clean profile? Actually, my first guess would be Sync (if enabled).

Oh, we will need to know what version of Linux and desktop environment you are using.
