Here’s how you can fix Call of Duty Black Ops 7 Beta from crashing on your PC due to Error Code 0x3 and more.

The Call of Duty Black Ops 7 Beta launch has been marred by several technical issues. PC players are experiencing random crashes and launch failures and are even unable to access the game’s content. Based on the official patch notes and troubleshooting resources, the following are confirmed causes of crashes. Below, we’ve listed the problems along with their possible solutions.
Note: These fixes are not official and may not work for everyone.
1. Black Ops 7 Beta Crashing: Missing or Disabled TPM 2.0 and Secure Boot

It is compulsory that PC players must have TPM 2.0 and Secure Boot enabled to launch the Beta. If you do not meet these requirements, running the game will result in a crash to desktop, as they are mandatory for the RIOCHET Anti-Cheat system within the game.
Resolution: Check TPM status via “tpm.msc” in the Windows Run menu; ensure that TPM and Secure Boot are activated in the BIOS/UEFI settings.
2. Dual Installation Sources (Error Code 0x3)

Players may experience crashes if they have the game installed and launched simultaneously from multiple platforms. For example, from the Xbox app (via Game Pass) and Steam.
Resolution: Uninstall the game from one source and then try relaunching it.
3. Outdated System Components

If you are using outdated graphics drivers, then the game will likely crash or experience frame pacing issues. Additionally, if the game files become corrupted, the game may also crash.
Resolution: Update your graphics drivers to the recommended versions provided by the developers. For files, use Steam’s Validate Game Files feature or the Xbox app’s Gaming Service Repair Tool.
4. Unstable System Components

If none of the solutions or fixes are effective, then you may have system components that are nearing the end of their life. We recommend optimizing your graphics settings to match your hardware, which can help reduce strain on your CPU and GPU. If you have applied CPU undervolt or RAM overclock, head to your motherboard’s BIOS and restore default settings. This should resolve crashes caused by system instability.
5. Overheating System Components

If your CPU or GPU cooling is inadequate, then the game is likely to crash. We recommend capping frame rate to your monitor’s max refresh rate with our optimized settings in action. This should significantly lower power draw and reduce heat output, saving the game from crashing due to thermal throttling.
