UE4 Fatal Error Windows 10

Hi all,
I have been trying to play Halo Reach on my Dell XPS 15 9560 running Windows 10 and I keep crashing after one or two games of multiplayer (always mid game, never in lobby). My error is a popup that says “UE4 - Fatal Error” and the game crashes when I click ok. Sometimes I can alt - tab out of the error and continue to play for a few minutes before crash, although in-game sounds are gone but menu sounds work.
I have tried the following:
<ul class="_33MEMislY0GAlB78wL1_CR"> - Every in game display option

  • Updating Windows and drivers
  • Verifying game cache
  • Running the launcher and anti-cheat as admin
  • Repairing the anti cheat (with and without admin privileges)
  • Uninstalling and reinstalling the game
    [/list]I checked Event Viewer in Windows as well and the event error says it’s trying to reach an invalid memory address.
    This is my favorite game of all time and I am so disappointed that I cannot play without crashing. This error happens in Campaign, Firefight, and Multiplayer.
    Side note - my laptop is not the issue, I can run other games no problem. Thermals are fine with my undervolted CPU peaking at 80c.

Please, does anyone have a fix for this?
