Ubuntu Software not opening? [duplicate]

I'm new to Ubuntu/Linux. When I try to open Ubuntu Software it shows it's loading, but after a few seconds it stops and nothing happens. When I run snap-store in the terminal it says:

/snap/snap-store/518/usr/bin/snap-store: symbol lookup error:
/snap/snap-store/518/gnome-platform/usr/lib/x86_64-linux-gnu/libgtk-3.so.0:
undefined symbol: atk_plug_set_child"

snap remove snap-store

snap install snap-store --candidate

could be a workaround
