Windernburg wont load

When I started my game today I can't load Windenburg. Everything worked fine 2-3 days ago and I haven't added anything new to my game since then.

When i go to manage worlds and click on Windenburg the screen just go white and I can't go back to the world selector, the other worlds are fine.

I tried with another save and it worked fine so it seems that it's a problem with this particular save file.

I have done what I could come up with to try and solve the problem but it still does not work:

I've removed my entire mods-folder from the Electronic arts folder

I've repaired my game in origin

I've removed the "localthumbcache.package", which was suggested in another post

What else can I do without losing this save file?
