Description:
The game client crashes to desktop repeatedly, roughly every 1–2 hours of play (6–8 crashes in a 4-hour session). It happens both in-game on modded servers and in the main menu with no world loaded (exit dialog open), so it does not seem tied to gameplay load.

Crash details from the minidump:

• Exception: 0xC0000005 Access violation

• Faulting address: ArmaReforgerSteam.exe+0xC2DF85

• Instruction: call qword ptr [rax+0x48]. This is a virtual call on an object with an invalid vtable pointer (rax = 0x200000002, read at 0x20000004A).

• Earlier crashes on build 191843 show the same pattern with a null vtable (read at 0x48) and with 0xFFFFFFFFFFFFFFFF.

• The call stack is identical between builds (same relative frame offsets), so it is the same code path.

This looks like a use-after-free or race condition in an engine-side object.

Builds affected: 191843 and 192142
GPU / driver: RTX 3080 Ti, NVIDIA 595.97 and 616.64 (both crash)
OS: Windows 10 22H2 (build 19045), 16 threads, 32 GB RAM
Peripherals: TrackIR 5 (NPClient 5.5), Logitech devices (G HUB, DirectInput force feedback).
Mods: large server modpack (ACE dev builds, RHS, TAO, etc.)

Reproducibility: Sometimes (about one crash every 1–2 h)
