You cannot delete that data but you can prevent that to happen in future.
Look at the affected page URLs that Google noticed error 500.
Check in your browser, are those Lage loading fine?
If yes, skip it.
If no, fix it.
The error 500 is the most popular issue, happens generally due to conflict with two similar plugins, bad code. You need to check error logs in that case.
