Problem with multipage and animated loader

I have this problem below for a while. Any help will help

I’m using the Hydralit function to add multiple pages to my app. However, whenever I change pages or load some functionality, a very large animated loader appears, which makes the app a little confusing (pictured below). Is there any way to remove it?

Or is there any other way to add multiple pages to the app that has a good design like hydralit, but without animated loaders?

Part of the code:

     page_title="Órbitas Relativisticas",

app = hy.HydraApp()

@app.addapp(title='Introdução', icon="📜")
def my_home():
    st.title("órbitas tipo-tempo para corpos massivos")

Animated loader:
