Latest Windows 11 update broke .NET Framework apps

Microsoft has updated the Windows 11 Known Issues page. The company noted that some .NET Framework 3.5 applications may experience problems after installing the latest KB5012643 update. Previously, this version of the system was causing screen flickering in safe mode and minor issues with File Explorer and Start.

For example, some .NET Framework 3.5 applications may stop opening after installing KB5012643. The error affects applications that use Windows Communication Foundation (WCF) and Windows Workflow (WWF) components.

Both solutions are stated to be workarounds. Microsoft said it was already working on a solution to the problems, but did not specify release dates for the updates that worked.
