I (23 F) asked my now gf(21 F) to be my girlfriend and she started playing minecraft. How do i deal with this?

I started dating my now gf 2 months back and just asked her to be my girlfriend I brought flowers and asked her. For a moment she was really happy and said yes, but then within a minute she went to her laptop and started playing minecraft and I dont know how to feel about that. I was hoping on her wanting to spend some time together or something more then her just saying yes and then going back in discord and playing minecraft with a friend. I dont really know how to deal with this, because I didnt expect her to play minecraft so fast after and am now thinking about breaking up I know her for a 2 months now and I really like her, but this seems realy surreal to me. Any reactions would be great, because I dont know what to do.
