App crashes on executeFetchRequest

I don't know what happened but it suddenly crashes on the following line in the Visibility.m Entity class. I did not change anything on these classes and it used to work perfectly. Only thing is that I deleted the model by mistake. I have restored it from backup and added it again to the project.

vis = [[context executeFetchRequest:request error:&error] lastObject];

This are the few lines around it

NSFetchRequest *request = [[NSFetchRequest alloc] init];
    request.entity = [NSEntityDescription entityForName:@"Visibility" inManagedObjectContext:context];
request.predicate = [NSPredicate predicateWithFormat:@"visID = %@",[tmpDict objectForKey:@"visiID"]];

NSError *error = nil;
vis = [[context executeFetchRequest:request error:&error] lastObject];

When failing it does not show any errors in console nor any other hints. It jumps to this line in main

int retVal = UIApplicationMain(argc, argv, nil, nil);

That is all...

any hints on how I could improve debugging or so? I have also tried to delete the app in the simulator but that did not workout as well.

AAH Finally I got an error message

But the keypath is there... I think there is some corruption... how can I solve this?

visID was missing in my model. Looks like I took an older version from backup
