Animation disappears in Lottie Editor

Hi so I’m developing an app and found the perfect splash screen on the website which I decided to edit the layer colours, but as soon as I change the second layer colour the entire animation disappears. Below is the file that I used to change the colours :

I am new to this site so I do apologise for not understanding the functions correctly

Hi @sudarshanvittal can you please provide a link to the animation file so I can test this as well.
