As it turns out, there are several different potential culprits that might end up causing this problem:
Method 1: Disabling the amBX service (if applicable)
If you’re seeing this type of crash at each attempt to launch GTA V, chances are you’re actually dealing with a conflict between the game and amBX (the lightning system) or a similar service. Several affected users that were facing the same problem have confirmed that they managed to fix the problem and launch the game normally after they accessed the Services screen and disabled the amBX service. After doing this and restarting their computer, most users have confirmed that the operation was resolved. If you’re unsure on how to do this, follow the instructions below: In case the same problem was still occurring, move down to the next potential fix below.
Method 2: Eliminating the 3rd party interference
If you’re encountering this particular issue while using File Explorer or when attempting to launch an application, it’s possible that you end up seeing this BEX64 crash due to a second software that is interfering with the launcher binary on memory (or vice versa). For some people, this was facilitated by an overprotective AV or firewall, while others blamed third-party themes and performance optimizers. A software called MacType (provides custom font rendering), DEDgear, AmBX, Razer Synapse and Teamviewer are most commonly reported for causing this type of crash. If this scenario applies, the solution is to start uninstalling the ‘suspect’ software to make sure that it’s no longer allowed to interact with other programs. In order to confirm if this is the case, you should start by achieving a clean boot state. if you can repeat the same action without seeing the BEX64 crash, you’ve just confirmed that the problem is indeed occurring due to a 3rd party process. Booting your computer in clean boot mode, takes a bit of work since you’ll need to ensure that only native Windows processes and startup items are permitted to run. If the clean boot state stops the same crash from occurring, you can begin to systematically re-enable the disabled items, coupled with frequent restarts to figure out which program is causing the problem. Once you manage to find the culprit responsible for the issue, follow the instructions below to uninstall it from your system: In case this scenario is not applicable or you’ve already uninstalled the problematic suite and you’re still facing the same issue, move down to the next potential fix below.
Method 3: Disable Data Execution Prevention
The data execution prevention filter is a set of software technologies that perform additional checks on the memory to prevent it from malicious code from running on a system. However, under certain circumstances, this security filter can become overprotective and prevent certain applications from functioning properly. This problem is frequently reported when users attempt to launch certain games that are built in such a way that they end up conflicting with the DEP environment. If this scenario is applicable, you should be able to fix the problem by disabling the data execution prevention filter with a swift CMD command:
