Vue components do not appear even with code in browser

I create an app, you can download it here GitHub - Lucy781228/Custom-App.
When using a 25 NextCloud server, the components work fine. But when I switch to a 22 NextCloud server, after editing the version in info.xml, here what’s I see:

I can see the code and component’s position when inspecting the page, but the components do not appear.

As u can see, the components are in the code, but they’re invisible.

Why there’s no one here.
