Windows exception -1073741819 0xC0000005

On Windows computers, after upgrading software or having left the computer on for days since last reboot (closing lid and reopening included), a memory Access Violation may occur:

  • exit code “-1073741819”
  • hex code 0x0005
  • Exception Code: 0xC0000005

The simplest and most common fix is to simply reboot the Windows computer.

We see these errors also during software development when building or configuring the build system such as CMake. Looking at the build directory file CMakeConfigureLog.yaml can provide more insights into the issue.
