In this article, we will discuss some possible solutions that may help to fix the unexpected access violation error on Windows 11/10 PC. Let’s see how:

Method 1: Disable Data Execution Prevention (DEP)

DEP or Data Execution Prevention is a method that protects your PC from any viruses or other external threats that can damage it to protect system security. Additionally, it monitors whether the programs on your PC are using RAM safely and not causing any harm. Therefore, if any program is found to be executing code in a way that is harmful to your system, DEP will forcefully close the program. However, if you trust the program, you can add an exception to DEP and disable functionality for that specific program. Let's see how:

Step 1: Press the Win R keys simultaneously on your keyboard to launch the Run command window.

Step 2: In the Run command text field, type sysdm.cpl and press Enter to open the System Properties window.
