AUR 2.7.1 to flatpak 2.8.0 cannot find installed games

I am using Manjaro Linux KDE to play games with the Heroic Games Launcher. The first version I downloaded and used to install my games was version 2.7.1 from the AUR. Suddenly, every time I tried to play, it would crash. I thought it might be due to the 2.8.0 update that was released. So, I decided to update by downloading the Flatpak version. I'm not sure what the difference is between the two versions, and I would appreciate it if someone could explain it to me. However, the problem is that the launcher is not recognizing the games I have already downloaded. Can someone help me make it detect my games?
