“WPP: Couldn’t read JSON data”

Hello,

I am using WPP from few months without any issues on my wordpress site and today all of a sudden it stopped registering views so i looked at chrome console and it was giving this error “WPP: Couldn’t read JSON data” with link to this file /wp-content/plugins/wordpress-popular-posts/assets/js/wpp.min.js?ver=6.3.3

Steps i have already tried:-
1. Activating/Deactivating
2. Install plugin again
3. Cleared cache multiple times
4. No minfiy option enabled in caching plugin (wp-rocket)

I tried health check and troubleshoot and when i installed default theme even with all plugins enabled WPP was working again. But i don’t understand why this is happening because everything is as it is from last few months no updates, no changes nothing.

Please help me to fix it ASAP.

Thanks.
