"Cannot access a disposed object" thrown OnClientDisconnect()

Hi there.

This error only occurs:

• on the server.
• when the client disconnecting is NOT also a host. Hosts stop perfectly fine.

The error seems to be caused by the base implementation of 'OnStopClient' called from the base 'OnClientDisconnect' method.

I am using the Multiplex Transport but currently only have Telepathy running.

I've tried first removing the client's ownership of all their owned objects as well as the player object. This did not help.

Here is the log:

ObjectDisposedException: Cannot access a disposed object.

(Filename: D:/Unity/Repos/WitheredWillows/Assets/Plugins/Mirror/Runtime/Transports/Telepathy/Telepathy/Server.cs Line: 324)

Currently I just commented out line 324 in Telepathy.Server which has the trouble method 'GetClientAddress' as seen at the top of the stack above.

Please let me know what further information I can provide. Thanks in advance for any assistance!

Start at Telepathy/Server.cs line 324, where GetClientAddress reads the client's remote endpoint during disconnection. Trace the callback path through TelepathyTransport.cs, MultiplexTransport.cs, and NetworkServer.cs, including the reported CustomNetworkManager.OnServerDisconnect call. Reproduce a non-host client disconnect and verify that the server no longer throws ObjectDisposedException.
