Windows 11 security update causes software crashes

Windows 11 security update causes software crashes

Microsoft has just released a May security update for Windows 11, but it is already causing problems. KB5013943 Version fixes only 75 vulnerabilities, but does not fix the application crash error. In fact, its installation exacerbates the problem

The problem affects applications that use the NET Framework. According to the latest Windows reports, users have complained about the following programs through the Microsoft Contact Center.

  • Microsoft Teams
  • Discord
  • ShareX
  • KeePass
  • Visual Studio Installer
  • Corsair ICUE
  • Corsair Service

The error does not affect all users of these programs, but if you see this error message, you know what caused it:

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

In general, if you have not installed the update, it is worth postponing it. This is technically mandatory, so it can be downloaded automatically in the background, but the installation requires a reboot, which you can avoid.

Microsoft has not yet released an amendment, but two unofficial solutions may solve the problem for you

While we are waiting for the official patch, there is another potential solution. The error appears to be due to a compatibility issue between Windows 11 and the .NET Framework, so reinstalling both versions 3.5 and 4.8 should resolve it. Here’s how to do it

  1. Click the search icon next to the Start menu, then type “Turn Windows features on or off.”

  2. Click the “Windows Update” button in the left pane, then the “Update History” button.

5. When done, restart your device to apply the changes

If this does not resolve the issue, it may be due to a previous optional update in which the first reported program crashed. In this scenario, or if more than a day has passed since the update was installed, you should wait for Microsoft to release the patch.
