I keep getting the below error while trying to import my data from CRA

Oops, we encountered an error

What happened to my data?

Don't worry! With the exception of the last page you were on, all the data you have entered so far has been safely saved on our secure server

I tried changing browsers and clearing cache but nothing works !
