On the laptop listed in my sig, Windows Explorer will crash and reset itself while trying to load the Reliability Report from the Windows Action Center. This just started today and doesn’t happen every single time when generating the report. It only happens when I exit out of the report and then reload it very fast by pressing the back and forward keys in quick succession on my mouse. When I do this, the window will hang on the screen with the green loading bar that says “Reliability Monitor is generating the report. Please wait…” and a new popup will appear telling me that Windows Explorer has crashed and is resetting itself. I would be very grateful if somebody can please interpret the error report of this incident and tell me how I can fix the problem.

Users of BEX64 system crashes usually report crashes after third-party applications or games crash. Crash activity usually occurs randomly or when complex tasks are performed.

Using certain third-party applications with the File Explorer causes the Bex64 error, which is a Windows-specific error. By updating the application or changing a setting in File Explorer, you will be able to fix this error, which is caused by a conflict between the application and the File Explorer.

A problem event called BEX64 indicates that the application has stopped working.

What Causes a Bex64 Error in Windows 10

The problem event name is BEX64, the application name is GTAVLauncher.exe, the application version is 1.0.323.1, and the application timestamp is 5527eec6. The fault module name is StackHash_1e37.

Blocked by Data Execution Prevention filter: It is also possible that the application that is being blocked is operating below the rules imposed by the DEP filter. If this scenario applies, and you trust the application, you can probably solve the problem by disabling the filter using the Advanced CMD query.

Various third-party failures: According to some affected users, this problem can also occur after a failure of an overprotected AV package, MacType, DEDgear, AmBX, Razer Synapse, or Teamviewer. In this case, you need to boot your computer to identify the culprit and then remove it through official channels.

It is pointing to the following error path: C:/Windows/System32/DriverStore/FileRepository/realtekservice.inf_amd64_f31d3fd59f245137/RtkAudUService64.exe.

When the GPU drivers are reinstalled, the computer usually stops outputting video, instead crashing out.

Interfering with the amBX service: If you see this error when trying to run GTA V, and you previously installed a Lightning custom module such as amBX, it is likely that you are dealing with a conflict between the two processes. In that case, you can fix the problem by going to the Services menu and disabling the amBX service.
