Cannot read sudden images

I am trying to copy an image and then use that copied version of the image. BitmapImage gives an exception saying "Cannot find image path"

BitmapImage image = new BitmapImage(new Uri(fullImagePath, UriKind.Absolute));

BitmapImage image = new BitmapImage(new Uri(fullImagePath, UriKind.Absolute));

Even tho a lot of other images works, only specific images does not work, can it be because of the size? I am using a filter, but that should not be making any errors

Microsoft.Win32.OpenFileDialog openFileDialog = new Microsoft.Win32.OpenFileDialog();
openFileDialog.Filter = "Image Files (*.jpg; *.jpeg; *.gif; *.bmp; *.png)|*.jpg; *.jpeg; *.gif; *.bmp; *.png";

Microsoft.Win32.OpenFileDialog openFileDialog = new Microsoft.Win32.OpenFileDialog();
openFileDialog.Filter = "Image Files (*.jpg; *.jpeg; *.gif; *.bmp; *.png)|*.jpg; *.jpeg; *.gif; *.bmp; *.png";

✅ Accsessing Method in another class by object

I have a customer class which contains the method I want to access

        public override void GetAllVichles(List<Enrollment> en)
        {
            //en.Sort();
            foreach (var enrollment in en)
            {
                foreach (var item in enrollment.Enrollments)
                {
                    if (item.CustomerInfo.FirstName == FirstName && item.CustomerInfo.LastName == LastName)
                    {
                        Console.WriteLine($"{item.CustomerInfo.FirstName} {item.VichleInfo.vichleList}");
                    };
                }
            }
        }

        public override void GetAllVichles(List<Enrollment> en)
        {
            //en.Sort();
            foreach (var enrollment in en)
            {
                foreach (var item in enrollment.Enrollments)
                {
                    if (item.CustomerInfo.FirstName == FirstName && item.CustomerInfo.LastName == LastName)
                    {
                        Console.WriteLine($"{item.CustomerInfo.FirstName} {item.VichleInfo.vichleList}");
                    };
                }
            }
        }

I want to call that method in my program.cs inside my foreach

                        Console.WriteLine("Write name of customer");
                        string customSearch = Console.ReadLine();
                        foreach (var item in vichle.vichleList)
                        {
                            if(customSearch == item.Owner.FirstName)
                            {

                            }

                        Console.WriteLine("Write name of customer");
                        string customSearch = Console.ReadLine();
                        foreach (var item in vichle.vichleList)
                        {
                            if(customSearch == item.Owner.FirstName)
                            {

                            }

It is supposed to search for customers with the written name Thanks beforehand 🙂

WPF read and write to Json [Answered]

The title says it all, I don't know how to read and write to Json properly. I tried some things but they don't seem to work

        static List<persondata> persondata()
        {
            string fileName = @"C:\Users\elko\source\repos\JsonData\JsonData\bin\Debug\net6.0-windows\Persons.json";
            if (File.Exists(fileName))
            {
                var persons = JsonConvert.DeserializeObject<List<persondata>>
                    (File.ReadAllText(fileName));

                return persons;
            }
            return null;
        }
    }

        static List<persondata> persondata()
        {

            }
            return null;
        }
    }
