@rama First, I would suggest that if you're using Windows, then please go to FAF client > top left menu > Settings > Forged Alliance Forever > Use FAF Debugger when starting Forged Alliance > > click "Get the latest version of the debugger". This will create a more detailed log to assist with troubleshooting.
Second, You have a sound bug which you can tell by the SND/XACT warnings. Simple fix steps are:
- Windows key > type: Control Panel > Open > Sound > Playback > select the Device you use:
- Configure > Stereo > finish configuration,
- Properties:
- Enhancements > Disable all enhancements,
- Advanced > 16 bit, 44100 Hz,
- Spatial Sound > Off,
- Restart or Shift+Shutdown (not just Shutdown) of PC
If your headphones come with any applet/program, then you may want to disable that & try using the headphones without it. Similarly, if they use a USB or Bluetooth dongle to connect to the PC, see if you can connect directly without the dongle.

Third, all versions of SCFA hates Alt+Tab or other things that take focus away while playing in full screen as indicated by the line info: Minimized true
in your log, so if you're going to do that, then it's highly recommended that you play in Windowed (if you're not already doing so). There are programs like Borderless Gaming or scripts like one of the ones in this FAF forum thread to make the window fit the entire screen so it appears that you're playing in full screen even though you're not.
Forth, after taking the corrective actions stated above, please try playing with all mods disabled in both the FAF Client & the in-game lobby to ensure that your base FAF game is working correctly. If you still crash with all mods disabled in both locations, then please post the new game log & replay# for those that can help to have for review.
