The 0x00000011 or THREAD_NOT_MUTEX_OWNER error usually occurs when a thread attempts to release a mutex that it does not own. A mutex, or mutual exclusion object, is a program object that allows multiple program threads to share the same resource, such as file access, but not simultaneously. This error can be a result of a software issue, particularly in the synchronization of threads.

How to fix:

  1. Software Debugging: If you’re a developer and this error occurred in your software, debugging your code to check for incorrect synchronization of threads or misuse of mutex objects is the first step. It’s important to ensure that mutex objects are correctly acquired and released in your software.
  2. Update Your System and Drivers: Always ensure that your operating system and all your drivers are up-to-date. Windows updates often include patches that fix potential bugs, and outdated drivers can cause issues.
  3. Uninstall Recent Software or Drivers: If this error started appearing after you installed new software or drivers, they could be the cause. Try uninstalling them to see if it resolves the issue.
  4. Run System File Checker (SFC): The System File Checker tool can identify and fix potential issues with your system files. Open Command Prompt as an administrator and type “sfc /scannow” to run this tool.
  5. Use System Restore: If the problem started recently, you might be able to fix it by rolling back your system to a previous state when everything was working correctly.
  6. Contact Support: If none of the above steps resolves the issue, it may be best to contact Microsoft Support or a professional technician for further assistance.

As always, ensure that you back up all important data before making any major changes to your system to avoid potential data loss.
