Hi @kishan

I think that your message could have been cut.

Could you share the full error message to _core.default is not a constructor and the steps to replicate the issue?

in this case, it seems like an import/export issue.

Did you follow all of the steps mentioned in the React installation guide at https://handsontable.com/docs/react-data-grid/installation/?

If so, please remove the node_modules and rerun the npm i to fetch dependencies. After that check if Handsontable is correctly imported to the component.
