Windows 10: .NET update breaks Windows defender

Hello,I just installed Windows 22H2 update. After the update Windows Defender worked fine until Windows installed .NET update KB5017026. The same thing happened in July when I installed Windows 11 for the first time. There was a .NET update that broke the Defender. Event log shows Event 7024 from Service Control Manager: The Windows Defender Firewall service terminated with the following service-specific error: The parameter is incorrect.As the firewall does not work I cannot use several applications that need firewall configuration changes.Any help would be appreciated.Timo
