Delay in Call and Camera Activation on Telegram Desktop (Windows)

[tozxart]

Steps to reproduce

Initiate a call by pressing the call button. Observe the delay before the call UI appears. Press the call button again to start the call. Observe the additional delay before the call starts. Activate or disable the camera during the call. Observe the delay in camera activation or deactivation.

Expected behaviour

The call UI should open immediately after pressing the call button. The call should start without any noticeable delay. Activating or disabling the camera should also happen instantly.

Actual behaviour

There is an 8-second delay when opening the call UI. There is an additional 8-second delay when starting the call. Activating or disabling the camera also takes around 8 seconds.

Same here! Every time I start or receive a call the client gets stuck for a while before the call starts. I'm using Telegram Desktop v5.5.1 x64 on Windows 11 I tried uninstalling and installing the client again but got the same result. It may be related to the version? Because this started happening to me suddenly.
