I discovered a workaround regarding this, after opening Opera, I just drag a tab and after releasing it anywhere in the screen the Opera account profile picture shows up.
And the rest places still use the habitual light blue color.
I don't know where they get the design ideas from, but these ideas look weird. And bad thing is that they don't care about taking into account feedback on the forum given a separate threads for Opera One.

Da*n, this crash removed my open tabs also 😞 Well, fortunately I have got some "Undo closed tabs" extension, which helped to restore them easily 🙂
@leocg I reinstalled Opera. I didn't uninstall first. Then I went through and rechecked all the sound settings to make sure the defaults were correct for all applications and devices. That seemed to fix the issue.
