I was undocking from Federation station, flying towards Leviathan. While there, I escorted the Ellydium Transport, then headed back to Eden Warp-Gate.
While flying back, the sound suddenly got stucked or looped.
I waited for 3 minutes, but game did not resume and stopped responding. I had to close the game by force and so I got a message that Star Conflict Client crashed.
If you need DxDiag log, you can check my other bug reports. My computer configuration and setup is the same.
Logs are provided here: (I am not sure, if Logs detected the issue)
