The cornavirus is causing a lot of havoc across the world, and in this case - Japan.
Many different shows have been delayed or cancelled, whether they're airing or not, and Re:Zero Season 2 is one of them.
The anime was originally planned for April 2020, as I already covered. But their official website confirmed it's being pushed back to July 2020. Unless they end up pushing it back more or changing the dates when everything is smoothed out with the cornavirus scare.
