WordPress Cannot Load Posts Editor

When I try to load https://example.com/wp-admin/edit.php I keep getting everything but the posts and where the posts should be it says “There has been a critical error on this website. Please check your site admin email inbox for instructions”

I checked my inbox and there is no message. There is one from yesterday for an identical error, but nothing from today. The error from yesterday happened while running WP All Import. I had to remove the last 10 posts, split the last import file, and resume from there.

How is it possible for WordPress not to be able to load the posts editor?
