KB5013943 May 2022 update crashes apps on Windows 11

Written by admin

If you’ve installed the May 2022 Cumulative Update on Windows 11, you may have noticed that many of the apps you always use don’t work like they used to. KB5013943, the mandatory security update, crashes certain apps that use the .NET Framework. In some cases, users get an error code: 0xc0000135

A similar issue was reported in the optional update, but it was not widespread. The bug seems to have slipped into the production channel with the May 2022 update and more users will be affected this time. The crashes are common with apps that use .NET Framework and apps like Discord or Microsoft Teams are also affected.

Looking at Microsoft’s Feedback Hub, it is confirmed that app crashes started earlier today after the release of May 2022 updates. The culprit seems to be a compatibility issue between the NET framework and Windows 11. For those who don’t To know, the .NET framework is a software development framework for building and running apps on Windows.

According to the reports we received, many apps appear to be affected. For example, the Corsair ICUE app does not work after installing the update, Corsair Service does not start and users keep getting error messages.

Some people have also flagged issues with ShareX, KeePass, Microsoft Teams, and other apps like the Visual Studio installer. One user on Feedback Hub claimed that they are unable to start Microsoft Teams due to the error message “process closed with code 3221225781 (0xc0000135)”.

“I just installed Windows 11 Update KB5013943 and it breaks the Sound Blaster Command app. The app didn’t start, instead I get the error message “sound blaster command could not start 0xc0000135 correctly”. Uninstalling the KB5013943 update solves the problem”, another user noted

How to troubleshoot KB5013943 on Windows 11?

Since the issue appears to be .NET Framework related, some users are reportedly getting the following error after installing the May 2022 Cumulative Update:

“The application could not start correctly (0xc0000135). Click OK to close the application”.

If you’re bothered, there isn’t an official fix yet, but users have told us that reinstalling .NET frameworks (both 3.5 and 4.8) should fix the problem.

If the .NET framework is not installed, you must enable it manually. If it’s already enabled, you’ll need to disable and re-enable it to fix the problem.

Follow these steps to resolve app crashes caused by Windows 11 May 2022 Update;

  1. Open Windows Search
  2. Search “Enable or disable Windows features
  3. Enable and disable all .NET frameworks.
    KB5013943 0xc000013 app crash fixed
  4. Click OK.
  5. Reboot your system.

We’re not sure what caused the problem, but simply enabling the .NET frameworks fixes the problem.

In some cases, users also encounter Blue Screen of Death errors, with one Feedback Hub poster report:

“After installing 2022-05 Cumulative Update for Windows 11 for x64-based Systems (KB5013943) and 022-05 Cumulative Update for .NET Framework 3.5 and 4.8 for Windows 11 for x64 (KB5013628), the Microsoft Studio 2 would not start with the generating error BSOD “APC_Index_Mismatch”, The only way to boot the machine was to reboot and then choose “reboot” on the maintenance screen. Then it would boot to the OS, repeat the error on the next shutdown, and reboot. The problem seems intermittent”.

If for some reason you can’t find .NET Framework in the Add or Remove Features popup, you can also search for it on Microsoft’s download website

How to Uninstall Windows 11 May 2022 Update

Uninstalling a Windows update is especially helpful if your computer is acting strange after a recent patch has been implemented.

It is generally a good idea to install security updates as soon as possible and we do not recommend uninstalling the security updates unless necessary. If your device isn’t in a usable state, you’ll want to be able to roll back security updates so you can fix app crashes or Blue Screen of Death errors until a new update can be released.

Fortunately, it is still possible to remove a security update if you installed it today or yesterday:

  1. Open Settings
  2. click on Windows Update
  3. Click on the Update history page.
  4. Locate Uninstall updates option under the “Related settings” section.
  5. Select the update.
  6. click on remove
  7. Restart
