How to fixSTATUS-ACCESS-VIOLATION

Memory Access Violation (STATUS_ACCESS_VIOLATION)

What this error means

STATUS-ACCESS-VIOLATION is a medium-severity software runtime problem. A process attempted to read or write to a memory address to which it does not have appropriate access permissions. Extremely common in web browsers (Chrome, Edge) and gaming applications. This can also stem from unstable RAM overclocking (XMP/EXPO) causing calculation discrepancies. See the troubleshooting steps below for the fix.
