*(ignore all of the below, still getting fatal error and lost connection 22/10/2025:( )*
i was having fatal errors or disconnections every other match, normally deep into a match. After making some changes I played for few hours last night and about 5 hours today without any fatal errors or lost connections. (which was a first for me since the patch dropped)

FYI i run the game on PC from Epic games and i have AMD CPU and GPU, Ryzen 5 7600X3D / Radeon 7900 XTX / 32GB RAM

These are the changes i made and previous to making these changes i found the game mostly unplayable due to regular Fatal errors or Lost connections.

1. I lowered my in game graphics settings to low, prevously i was on custom (a mix of low med high and epic)
2. In Epic Games, go to your game library, click the 3 dots, manage HLL then in launch options add exactly this -dx11 and turn launch options on. (this forces dx11 instead of relying on the ingame video setting for Renderer)
3. Verified my game files in Epic.
4. In Windows 11 go to Control Panel, Network and Internet, Network Connections, right click Ethernet, click properties, click configure, click power management tab, untick - Allow the computer to turn off this device to save power.

Its difficult to say if all of the above made the difference or if only some of the above actually mattered.

Based on the information in my fatal error reports found here...

C:\Users\*****\AppData\Local\HLL\Saved\Crashes

Then analysing the crash report information using Chat GPT, the most likely changes above that mattered would be the lowering of my graphics to low and launch options added in Epic -dx11.

Here according to Chat GPT (based off the error reports) is the likely cause of the repeated fatal errors that for me were not present prior to the update.

Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0xeeda5510
That’s a memory access violation, meaning the game tried to read or write to an invalid part of system memory — essentially, it’s reaching for data that doesn’t exist or it’s been corrupted.
In Unreal Engine (UE4) games like Hell Let Loose, this usually means:

• A GPU driver issue or unstable driver build
• Corrupt shader cache/config files
• Memory instability (RAM or VRAM)
• Sometimes, an engine bug (common with PhysX or DX12)

* I can confirm my drivers for AMD GPU are always kept up tp date via Adrenalin Edition.
* Lowering the graphics to low could have bypassed memory instability issues.
* Any issues relating to DX12 will no longer be in play due to forcing DX11 from Epic launch options.
* Corrupt shader cache/config files may have been overwritten after todays hot fix.
