If you have installed the May 2022 Cumulative Update on Windows 11, you may have noticed that many of the applications you use all the time are not working as usual. KB5013943, the mandatory security update, disables some applications that use the .NET framework. In some cases, users receive an error code: 0xc0000135.
A similar issue was reported with the optional update, but it wasn’t widespread. The bug seems to have crept into the production channel with the May 2022 update and more users are affected this time around. Crashes are common among applications that use the .NET Framework and applications such as Discord or Microsoft Teams are also affected.
Looking at Microsoft’s Feedback Center confirms that application crashes started earlier today after the release of the May 2022 updates. The reason behind this seems to be a compatibility issue between the .NET framework and Windows 11. For those unaware, the .NET framework is a framework for development Programs to create and run applications on Windows.
According to the reports we received, it appears that several apps have been affected. For example, Corsair ICUE app doesn’t work after installing an update, Corsair service fails to start and users keep getting error notifications.
Some people have also reported issues with ShareX, KeePass, Microsoft Teams, and other apps like the Visual Studio installer. A user in the Feedback Center claimed that he was unable to run Microsoft Teams due to the error message “The process terminated with code 322125781 (0xc0000135).”
“I just installed Windows 11 Update KB5013943, and it breaks the Sound Blaster Command app. The app won’t start, instead I get an error saying “Speaker command is unable to start properly 0xc0000135″. Another user noticed that uninstalling the KB5013943 update fixed the problem.
How to fix KB5013943 issues on Windows 11
Since the issue appears to be related to the .NET Framework, some users are reported to receive the following error after installing the May 2022 cumulative update:
The application could not start properly (0xc0000135). Click OK to close the application.
If you’re affected, there’s no official solution yet, but users have told us that reinstalling the .NET frameworks (both 3.5 and 4.8) should fix the problem.
If the .NET framework is not installed, you need to enable it manually. If it is already enabled, you will need to disable it and enable it again to fix the problem.
To fix application crashes caused by the Windows 11 May 2022 Update, follow these steps;
- Opens Windows search.
- research “Turn Windows features on or off“.
- Disable and enable all .NET frameworks.
- Click OK.
- Reboot your system.
We are not sure what caused the problem, but simply running the .NET framework solves the problem.
In some cases, users also encounter Blue Screen of Exception errors, with one of the posters reporting in the feedback center:
After installing Cumulative Update 2022-05 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), Microsoft Studio 2 fails to generate boot error BSOD “APC_Index_Mismatch”, the only way to get the device to work is to reboot and then choose “reboot” on the maintenance screen. Then it boots into the OS, and the error repeats again at the next shutdown and restart. The problem seems to be intermittent.”
If for any reason you cannot find the .NET Framework in the Add or Remove Features window, you can instead search for it on the Microsoft Downloads website.
How to uninstall the Windows 11 May 2022 Update
Uninstalling a Windows update is certainly useful if your computer is behaving strangely after a recent patch has been deployed.
It is generally a good idea to install security updates as soon as possible and we do not recommend removing security updates unless it is necessary. If your device is not 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 is released.
Fortunately, a security update can still be uninstalled if you installed it today or yesterday:
- Opens Settings.
- Click Windows Update.
- tap on Update date page.
- Locate Uninstall updates option underRelated settings” Section.
- Select Update.
- Click uninstall.
