Destroyed Photo Development Module

Hey Community!

I have one big issue and don't know what to do further.

When i check my pictures in my library of Lightroom CC everthing is fine.

The problem occurs then, when I switch over to the develop module to edit my photos.

It looks like on the screenshot i attached.

There wasn't any update between working normally and the occuring of the error...

What went wrong? Can anyone please tell me?

Thx a lot!
