The installation was done from command line
sudo apt get-install anki and when tried to run through command line by just typing
anki, it showed the following
Qt warning: QApplication: invalid style override 'adwaita' passed, ignoring it. Available styles: Windows, Fusion mpv too old for key rebinding LaunchProcess: failed to execvp: /usr/local/share/anki/bin/PyQt5/Qt/libexec/QtWebEngineProcess Trace/breakpoint trap
