Sudden Error Message From Happy Hop

I have been playing Hoppy Hop for months now and suddenly it showed this error message.

It works on other devices but not my main phone. It has higher specs too so it shouldn't be that.

I tried some self troubleshooting like reinstall, clear cache data and so on and some research as well.

Any help would be appreciated .
