ACCESS_VIOLATION - The instruction at "0x00007ff7d6f0fbf8" referenced memory at "0xffffffffffffffff"

I’m getting contant ACCESS_VIOLATION - The instruction at “0x00007ff7d6f0fbf8” referenced memory at “0xffffffffffffffff” when playing the beta. Works fine in Retail and/or other games. No addons. I’ve tried updating BIOS even.

This is the crash report located at C:\Program Files (x86)\World of Warcraft_beta_\Errors

Running the report by an AI agent:

Core Issue

ACCESS_VIOLATION (Memory Read Error) - The game tried to read from an invalid memory address 0xffffffffffffffff (all F’s = -1, a null/invalid pointer).

Key Details

What happened:

  • When: ~12 minutes into gameplay after attacking a training dummy

  • Where: Contender’s Gate, Dornogal

  • Character: Night Elf Rogue (Outlaw spec) on Halduron realm

  • Activity: Combat with “Cleave Training Dummy”

Technical indicators:

  • Clean beta build (64339) from Nov 7, 2025

  • No addons loaded (<Addons.HasAny.Loaded> No)

  • Zero Lua errors

  • System stable (20 min uptime, good hardware - RTX 3080, 32GB RAM)

  • Using D3D12 renderer with NVIDIA drivers

Likely Cause

The crash stack trace shows the exception originated deep in WoW’s rendering or combat calculation code. Given you were:

  1. Attacking a training dummy with AoE abilities (Cleave dummy)

  2. Playing Outlaw Rogue with various combat effects active

  3. Had spell clutter/density settings at moderate levels

This appears to be a beta bug in combat spell effect handling - possibly a race condition where the game tried to access a spell effect or combat log object that was already deallocated or not properly initialized.

What You Can Do

  • Report this to Blizzard via their beta bug report system

  • Try reproducing: Does it crash consistently with the same rotation on training dummies?

  • Consider lowering spell density settings temporarily (spellClutter, particleDensity)

This is a legitimate bug in the beta client, not something wrong with your system. Your hardware and drivers look fine.

make the background fps and target fps as close to the monitor actual refresh rate .that fixed it for me

didn’t help. I’ve noticed that it happens mostly while around dummies, likely because there’s more people around doing stuff.
