[BUG] image assets disappear after updating party size multiple (unable to reopen issue #261)

[DutchCoder420]

I wasn't able to reopen issue #261 so i created a new bug report instead.

Versions tested

version	Result
1.0.175	Large/small image assets stay visible after countless UpdatePartySize calls
1.5.x ->1.5.0.51	Image assets disappear after a few party-size updates

On 1.5.x the image assets vanish after a few updates, leaving only text. No errors are thrown; Discord simply stops showing the image. Rolling back to 1.0.175 restores correct behaviour.

here is a basic console app sample

internal class Program
{
    private const string ClientId = "DISCORD_RPC_TOKEN";

    private static DiscordRpcClient _client;
    private static Timer _partyTimer;
    private static readonly Random _rng = new();

    static void Main()
    {
        _client = new DiscordRpcClient(ClientId)
        {
            Logger = new FileLogger("discord_rpc.log")
            {
                Level = LogLevel.Trace,
            }
        };
        _client.Initialize();

        _client.SetPresence(new RichPresence
        {
            Details = "Testing RPC Bug",
            State = "Waiting image to dissapear…",
            Timestamps = Timestamps.Now,
            Assets = new Assets
            {
                LargeImageKey = "https://i.imgur.com/VxYHUTk.gif",
                SmallImageKey = "https://i.imgur.com/VxYHUTk.gif",
            },
            Party = new Party
            {
                ID = Guid.NewGuid().ToString(),
                Size = 1,
                Max = 100,
            },
        });

        _partyTimer = new Timer(UpdatePartySize, null, TimeSpan.Zero, TimeSpan.FromSeconds(10));

        Console.WriteLine("RPC running – press any key to exit…");
        Console.ReadKey();

        _partyTimer.Dispose();
        _client.ClearPresence();
        _client.Dispose();
    }

    private static void UpdatePartySize(object _)
    {
        try
        {
            int newSize = _rng.Next(1, 100);

            /* 
             * After a few party-size updates, the image assets vanishes from the Rich Presence. 
             * The issue appears only in versions **newer than 1.0.175**—that version (and earlier) retains the image without problems.
             * 1.0.175 works, when switching to version 1.5.0.51 you will see the images vanishes.
             */
            _client.UpdatePartySize(newSize, 100);
            Console.WriteLine($"Party size → {newSize}/100");
        }
        catch (Exception ex)
        {
            Console.WriteLine($"[RPC error] {ex.Message}");
        }
    }
}
