The DCS client and server quit with a "Login session has expired" popup when reconnecting to the master server after the connection had been lost for about half an hour. Said quitting now appears to trigger a delayed segmentation fault. Originally reported here.

Hello everyone, DCS is non stop crashing on me. Sometimes one thing works, then it crashes again after getting it going. then the fix won't work. Search for hours on forums and you tube videos and sometimes find another solution that works once or twice. One of the last crashes, I noticed, that I changed resolution to my projector and the game crashed. Changed the resolution back and the game work for a little bit. I have played with that resolution setting for hours before and had no issue. If its not one thing is another with DCS. I tried numerous things including reinstalling DCS, Windows (back and forth between 10 and 11), Drivers. I have set my page file, run as administrator, set DCS app to high performance in windows and nvidia control panel. Spent more time probably trying to fix DCS and get it working then flying at this point. This game is so awesome and I love flying, but its getting close to wanting to give up on DCS altogether. The these crashes are on start up, never while playing. It never gets past the LOGO on startup. Doesn't go black, just Logo pops up and then after 5 - 20 secs crash advisory window pops up. I know DCS is a delicate game and seems numerous people have so many of the same problems while others no problems at all. I'm not sure if its the same issue or a different one at this point but can someone take a look at these crash files and let me know if anything sticks out to them or something I should try. info on my pc: RTX4090, AMD Ryzen 5950x, 64gb of ram, ROG Crosshair VIII Formula MOBO, 1200watt PSU, 5 virpil hotas and panel devices (powered by USB hub), Winwing MIP( consisting of 4 devices and 3 MFD screens.

DCS open beta (i had numerous crashes when on stable too) Thanks everyone, Cheers. dcs.20230214-225913.crash dcs.20230214-225913.log dcs.20230214-230130.crash dcs.20230214-230130.log dcs.20230216-041045.crash dcs.20230216-041045.log dcs.20230216-041741.crash dcs.20230216-041741.log

Hi, running a new PC here, with DCS, which has been working fine for over 3 months. No issues. Now since a couple of weeks, getting constant crashes when in multiplayer VR, but also when running the game in non-vr mode. Edit: Im using a Quest 2 with openxr. Most recent crash files attached. I've tried the following things: - The source seems to be irratic, like attached, the error is thrown from DCS.exe, but I've seen it from weapons.dll and other files aswell. - Removed all custom mods like SRS and Tacview - Ran a stress test on GPU, removed drivers with DDU in safe mode and reinstalled Nvidia drivers. - Cleared out FXO and metashaders folder - Reinstalled DCS completely and ran a repair - reverted back to v62 of the oculus meta quest software manually, as this was marked as a solution somewhere on the forum I don't know when the issues began, but I had the feeling at first that it was caused by using ReShade, which I removed as soon as the issues started. But now, after reinstalling, I'm not so sure. I also switched from HDMI to Displayport cable, but since the issues are in VR only (and I've tested both cables afterwards) I dont really think this has something to do with it. I'm really puzzled as to what is the cause now, hope someone can help! dcs.log-20240511-204356.zip
