Issue: How to fix KB5013943 causing application errors?
Hello. I recently installed the latest Windows updates and I keep receiving errors when I try to open my applications. What could be the problem?
Solved Answer
Recently, Windows 11 users started experiencing errors when trying to launch certain applications. The issue seems to have started after people installed the latest KB5013943[1] cumulative update. The update was supposed to fix security vulnerabilities and bugs. Specifically, it had to fix a bug causing .NET Framework 3.5[2] apps not to open if they used the Windows Communication Foundation (WCF) and Windows Workflow (WWF) components.
However, now many people report specifically receiving the 0xc0000135 error when trying to use apps such as ProtonVPN, PowerShell, Event Viewer, Sound Blaster Command, KeePass, Visual Studio, Discord, and ShareX. The full error message reads as follows:
The application was unable to start correctly (0xc0000135). Click OK to close the application
