Modern Warfare 2 beta error code 0xc0000005(0) N: What causes it and how to possibly fix it?

sportskeeda.com:

The Call of Duty: Modern Warfare 2 Early Access beta is now online for PC and Xbox. However, gamers on computers have already reported frequent game crashes and performance hiccups. One of the most frustrating issues involves the title crashing with an error code: 0xc0000005(0) N.

The problem has been known to present itself within the lobby and not during a match. In it, the screen will lock up, and the game will proceed to crash to the desktop. While it doesn't spoil matches, it is certainly disrupting the gameplay experience. Although there aren't any permanent solutions to this issue, the tweaks and suggestions in this guide can help negate this problem to an extent.

The error code 0xc0000005(0) N generally occurs when the game cannot get access to the data it is looking for in the system's memory. When it doesn't find the required data, the game crashes. Player reports suggest that this error happens when they are in a lobby looking for a match. As soon as they get a match, the game seems to crash.

Outdated system drivers — regardless of audio, chipset, or GPU — can often disrupt the normal running of a game, causing it to crash. If the drivers aren't updated, it can cause a host of other incompatibility issues as well.

Anti-viruses are known to cause problems with games. They can block access to the memory for the game. Apart from this, they can also report false positives, which can shut down the game because the system thinks it is malware. Modern Warfare 2 comes with RICOCHET's kernel-level anti-cheat system, and these types of anti-cheats are known for creating conflicts with anti-virus software.

Third-party-overlay software such as Rivatuner Statistics, GeForce Experience, FRAPs, etc. can cause the game to crash.
