I'm experiencing a persistent ERROR #132 crash, and I'm trying to determine what's causing it.
Crash conditions
The crash only happens while I'm inside raid instances.
It occurs most often in 40-player raids.
After logging into my character, the game may crash at any random time, but it usually happens within the first 1–2 minutes.
If the instance is empty, the game never crashes.
If there are fewer than about 10 players in the raid, the crash either doesn't happen at all or becomes extremely rare.
What I've already tested
To rule out software issues, I tested with a completely clean client:
Fresh client.
No custom DLLs.
No client modifications.
No patches.
Only two very common addons.
The crashes still occur with exactly the same frequency.
Additional observation
The only thing that noticeably reduces the problem is running the game on my laptop's integrated intel GPU instead of the dedicated RTX4090.
Using the integrated graphics doesn't completely eliminate the crashes, but they happen much less frequently and can be delayed for a long time.
Has anyone encountered a similar issue or has any idea what could cause this?
I'll attach the ERROR #132 crash log below.
