Did an update to site and now I get 500 error on Files Module. If I go into the Files tablebuilder and remove
'entry.preview' => [
'heading' => 'anomaly.module.files::field.preview.name',
Then the error goes away.
It's rebuilding your previews so probably file exhaustion error. What do your error logs say? Try reloading a few times.
Please try and make your discussion titles more specific!
