If you installed the
May 2022 cumulative update on Windows 11, you might have
noticed that many of the apps you use all the time aren’t
working as they used to. KB5013943, the mandatory security
update, is crashing certain apps that use .NET framework. In
some cases, users are getting 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 May 2022 update and more users are
affected this time. The crashes are common among apps that use
.NET Framework and apps like Discord or Microsoft Teams are
also affected.
Looking at Microsoft’s Feedback Hub confirms that app crashes
started earlier today following the release of May 2022
updates. The culprit appears to be a compatibility issue
between the NET framework and Windows 11. For those unaware,
the .NET framework is a software development framework for
building and running apps on Windows.
According to reports received by us, many apps appear to be
affected. For example, the Corsair ICUE app does not work after
installing the update, with Corsair Service failing to start
and users keep getting error notifications.
Some people also flagged issues with ShareX, KeePass, Microsoft
Teams and other apps like Visual Studio installer. One user on
Feedback Hub claimed that they are
unable to launch Microsoft Teams due to the error message
“process exited with code 3221225781 (0xc0000135)”.
“I just installed Windows 11 Update KB5013943, and it breaks
the Sound Blaster Command app. The app would not start, instead
I get an error saying “sound blaster command unable to start
correctly 0xc0000135″. Uninstalling KB5013943 update fixes the
problem,” another user noted.
How to fix KB5013943 issues on Windows 11
Since the issue seems to be related to .NET Framework, some
users are reportedly getting the following error after
installing May 2022 cumulative update:
“The application was unable to start correctly
(0xc0000135). Click OK to close the application”.
If you’re affected, there’s no official fix as of yet, but
users have told us that reinstalling .NET frameworks (both 3.5
and 4.8) should resolve the problem.
If the .NET framework is not installed, you need to enable it
manually. If it’s already enabled, you will need to disable and
enable it again to fix the problem.
To fix app crashes caused by Windows 11 May 2022 update, follow
these steps;
- Open Windows Search.
- Search “Turn Windows features on or off“.
- Disable and enable all .NET frameworks.
- Click on OK.
- Reboot your system.
We are not sure what caused the issue, but simply turning on
the .NET frameworks resolves the problem.
In some cases, users are also running into Blue Screen of Death
errors, with one Feedback Hub poster reporting:
“After installation of 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 fail to boot
generating error BSOD “APC_Index_Mismatch”, The only way to
boot the machine was to restart and then on the maintenance
screen choose “reboot”. Then it would boot to the OS, repeating
the error again on the next shutdown and restart. The problem
seems intermittent”.
If for whatever reason, you can’t find .NET Framework in Add or
remove features pop-up, you can alternatively search for it on
Microsoft’s downloads
website.
How to uninstall Windows 11 May 2022 update
Uninstalling a Windows update certainly comes in handy if your
computer is acting strangely after the deployment of a recent
patch.
It’s generally a good idea to install security updates as soon
as possible and we don’t recommend removing the security
updates unless 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 can be released.
Thankfully, it is still possible to uninstall a security update
if you installed it today or yesterday:
- Open Settings.
- Click on Windows Update.
- Click the Update history page.
- Locate Uninstall updates option under the
“Related settings” section. - Select the update.
- Click on Uninstall.
- Reboot.
