Thanks, @shail-mehta! The related code in core has undergone significant changes in https://github.com/WordPress/wordpress-develop/pull/9810/files; can you update this to match?

I'd also like to see the code for the archives widget included in this: https://github.com/WordPress/gutenberg/blob/trunk/packages/block-library/src/archives/index.php.

The conflicts with this PR are basically the entirety of the PR at this point, since there have been significant changes to the category widget JS since this was started. So I'm going to go ahead and start a new PR to resolve this issue.
