❔ Problem with Dictionary<ulong, Image> (Strange work of memory access)

private static Dictionary<ulong, Image> UserStickerProfiles = new();

public static async Task MoveSticker(Sticker sticker)
{
    var stickerImage = await ItemManager.GetProfileItemImageAsync(itemId); // take image of sticker from file

    UserStickerProfiles.TryGetValue(args.User.Id, out var image);
    if (image == null)
    {
        image = await ProfileMethods.DrawProfileExceptStickerAsync(args.User, itemId); // draw picture without this sticker
        UserStickerProfiles.Add(args.User.Id, image);
    }

    image.Mutate(x => x.DrawImage(stickerImage, new Point(sticker.PositionX, sticker.PositionY), 1f)); // draw this sticker with new coordinations

    // saving and sending
    var memoryStream = new MemoryStream();
    await image.SaveAsPngAsync(memoryStream);
    memoryStream.Seek(0, SeekOrigin.Begin);

    // send image to user with memortStream
}
