Problem with Epub preview

[saikrishna231459270fzy]

I have made my design interactive and it is working fine but then I didn't like the appearance of my design so I changed the colors and positions a little bit but didn't change any button names or animations. now the epub preview is not working. please give me a solution for this

In the lower left corner of the EPUB Interactivity Preview panel is the Play button that is used to preview the animation. To the right of that button is the Clear Preview button. Does pressing that and then pressing the Play button help?

No, it didn't. I tried everything(closing, restarting the application, resetting the preference ). one more thing to add on is I didn't do any color changes to the rest of the pages and they work fine, it is this only page not working. I even published it online to check if it is working while published but no use.
