My web apps disappered from the build section of google ai studio

I was having 36-40 apps in my build section of AI Studios, but when I came back to work on some of them after my exam, only 15 were visible, and the rest just disappeared. What the hell is it?

Do I have to push all the updates to GitHub as soon as possible? After each time of working, just to get the apps saved?
