ntdll.dll file is causing an error | Crashing the application

Question

Hi there,

I have been receiving an error after updating to Windows 11 pro v24h2. Since this upgrade, we have been receiving an error in multiple laptops.

Prior to this version, in all the laptops the application was working (Prior Version was Windows 11 pro, version 23H2.)

Event Viewer shows an error:

faulting module name: ntdll.dll, version: 10.0.26100.3323

Exception code: 0xc0000005

Faulting module path: C:\Windows\System32\ntdll.dll

Source: Application Error

Task Category: Application Crashing Events

Level: Error

Methods I have tried are as follows:

1. Admin CMD --> SFC
2. Admin CMD --> DISM
3. Re-installing the Application
4. Clean Boot (reinstalling the windows)

Please let me know if there is any solution to fix this issue.

Best Regards

Answer 1

I'm receiving the same issues here.

The application that is crashing is currently Java based and from what I understand Java and 24h2 aren't working very well.

I am also looking into whether sentinelone is causing this, however it's more likely it's windows 11 24h2. Rollback to 23h2 if you can and block updates to 24h2 until further notice.

Answer 2

I am trying to use the Decryptor Dongle USB

Type: Application

Let me know if you need more requirements

Answer 4

Thanks for the solution. Unfortunately, it is still not working.

On the other hand, I cannot go back to the previous version. As our client cannot undo the latest version of windows due to some security reason, also we cannot proceed with the Virtual Machine (on our system). If there is any other option, please let me know.

Thanks!

Hello Ankit Bharti1, welcome to the Microsoft Community.
Thank you for your feedback. It's my honor to assist you with this issue.

When the ntdll.dll issue causes application crashes, it usually points to core problems in the operating system or compatibility issues with third-party software.
Problem analysis:
ntdll.dll is a key dynamic link library in the Windows operating system, responsible for handling various low-level functions, including memory management and exception handling.
When ntdll.dll encounters obstacles, it is usually caused by the following reasons:

1. The application is incompatible with the updated Windows version.
2. System file corruption (even though you have run the SFC and DISM commands).
3. Hardware driver issues.
4. Interference from third-party software or DLL injection.
5. Permission or configuration issues.
6. Potential errors in Windows updates (problems with the new version).
   Your ntdll.dll crash may be related to the changes after the 24H2 update, so the solution requires a step-by-step investigation of compatibility and system components.
   I would like to confirm with you whether the problem only affects specific applications? If so, it might be a compatibility issue and you need to confirm with the developer whether it supports Windows 11 24H2.

Method 1: Check Application Compatibility Settings
Test the crashed application in compatibility mode:

1. Right-click the application's executable file (.exe) and select "Properties".
2. Go to the "Compatibility" tab.
3. Check "Run this program in compatibility mode for" and select a version of Windows 10 or earlier.
4. Check "Run this program as an administrator".
5. Click "OK" and run the application to see if it still crashes.

Method 2: Registry Repair (To prevent possible permission issues)
Windows Update may have affected certain permissions in the registry. Try the following:

1. Press Windows + R to open "Run", and enter regedit.
2. Navigate to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WpnUserService 
3. Ensure that the current user has full control permissions for this key:
   Right-click on this registry key and select "Permissions".
   Make sure that the "Administrators" and "SYSTEM" users have "Full Control".

Method 3: Replace or Repair ntdll.dll
Although ntdll.dll is a core file of Windows, it is unlikely to be directly damaged. However, we can replace or repair it through the following methods:
Copy ntdll.dll from another machine (compatible version):
1. On an unaffected Windows 11 (version 24H2) computer, copy C:\Windows\System32\ntdll.dll.
2. Transfer it to the affected laptop, rename the ntdll.dll in the crashed device to ntdll_old.dll, and then paste and replace it.
3. Restart the system.

Method 4: Roll Back to Windows 11 23H2
If the previous methods do not solve the problem and your application runs normally on 23H2, it is recommended that you temporarily roll back the system and wait for Microsoft to release a suitable fix update for 24H2.

1. Open "Settings" > "System" > "Recovery" > "Go back to an earlier build".
2. Follow the prompts to complete the rollback.

We are always looking forward to your feedback again.
