Ubuntu 20.04不再支持Ubuntu软件

I have just upgraded to Ubuntu 20.04. Before the upgrade, the updater informed me that it would no longer support Ubuntu Software. After the upgrade is successful, I found that I can't open Ubuntu Software, but when I go to terminal and type gnome-software, I can use Ubuntu Software.

I also checked all the apps. I found that there are 2 Ubuntu Softwares in my system. One is named Ubuntu Software, which doesn't work at all and the other is named only Software

How can I fix this issue? How can I delete Ubuntu Software completely? Or is there another way to cope with this?
