Hello,
Arma Reforger repeatedly crashes to desktop during normal gameplay on WCS servers. Across the logs collected between October 27 and October 30, 2026, twelve crashes have the same executable-relative fault address and the same 15-frame call stack.
System:
Game version: 1.8.0.13
Platform: PC, Steam, Windows
CPU: Intel Core i5-14400F
GPU: NVIDIA GeForce RTX 4070 SUPER
GPU driver reported in the logs: 610.88
Affected servers:
Main crash:
Access violation, usually an illegal read at 0x18.
Fault location: ArmaReforgerSteam.exe + 0x8197CA.
One crash accessed a different invalid memory address, but the executable-relative fault location and call stack remained identical.
The crashes occur unpredictably, from approximately three minutes to more than two hours into a session. They have occurred during different activities, so I cannot identify a reliable trigger. In one instance, the game crashed shortly after I spawned a vehicle and entered it. Local Game Master testing with mods appeared stable.
Troubleshooting already completed:
Successfully verified the game files through Steam.
Removed and reinstalled all mods.
Renamed the profile folder and allowed the game to generate a fresh profile.
Tried the documented -singleThreadedUpdate launch parameter.
Tried different WCS servers and maps.
None of these measures prevented the recurring crash.
There is also a separate crash pattern in two earlier reports: network replication stalls, the connection is terminated, and the client then crashes in memmove/VCRUNTIME140.dll. The twelve crashes described above do not all have a preceding connection termination.

I am providing the logs and minidumps for investigation. Could you please symbolicate the recurring call stack and check whether it matches a known engine issue or points to a particular mod interaction?
Please let me know if you need a DxDiag report or additional diagnostic information.
Thank you.
