Current behavior

Since last 7 days newly uploaded/updated images are not accessible through the slug (link).
e.g. accessing https://squidex_url/api/assets/app-content/655.png via browser
results in

This page isn't working at the moment
<squidex_url> can't currently handle this request.
HTTP ERROR 500

Here is the relevant log

Mainly SixLabors.ImageSharp.UnknownImageFormatException is concerning. We have tried different formats. Even the images that worked before are now giving this error.

Expected behavior

Uploaded images are accessible through link.

Minimal reproduction of the problem

  1. Upload the image
  2. Access the image through link

I have no idea, perhaps the disk is broken or something like that. But your version is very old and I would probably not make a bugfix for that anyway.

This is a production cluster with thousands of active users, any help would be immensely appreciated.
Let’s say the disk has an issue.
Is there any way to solve this without losing data?

If the disk is really broken you have an issue, but you can verify that this is not the problem by just downloading the image directly from the source and verify its integrity.
