Arma Reforger crashing with 0xC0000374 heap corruption when shot/dying /bandaging
I’m trying to troubleshoot a recurring Arma Reforger crash that happens mostly when I get shot, die, or try to bandage on modded servers (specifically Spearhead UHC servers). I’m at a loss because I have a fairly strong PC and I never have issues in any other games ever.
I have played spearhead UHC servers since September, and this only started to happen as of a month or two ago (maybe a little more). I have had this issue occasionally on modded servers, but nothing like spearhead were it seems to happen at least 60-70% of the time I used bandages. I have looked far and wide and have never found another person with this same issue, all of my 20+ friends I play with never have experienced this issue. I really am at a loss with this one all around and don't really know what to try next to fix this.
Here is a list of all of the fixes I have tried based on what I could find online with other users with heap related issues.
Paused OneDrive syncing
Set the Arma Reforger folder to “Always keep on this device”
Deleted/renamed the entire Reforger folder in Documents/My Games
Deleted the temp addons folder in AppData/Local/Temp
Redownloaded all server mods from scratch
Verified Steam game files
Clean reinstalled NVIDIA drivers
Disabled overlays, including Steam/Discord/NVIDIA-style overlays
Checked Task Manager during gameplay
RAM usage was normal, around 19 GB used out of 32 GB
GPU temp was normal, around 64°C
GPU usage was normal, around 80%
VRAM usage was not maxed
Checked RAM speed
It is running at 4800 MT/s, so XMP is likely not enabled
Checked Event Viewer
It shows ArmaReforgerSteam.exe
Faulting module is unknown
Exception code is c0000374
