Does this issue occur with all troubleshooters or just networking troubleshooter? Have you tried to launch troubleshooters from different location? You can launch troubleshooters either from
Control Panel, Action Center or Related Topic in Help. How about unchecking "Get the most up-to-date troubleshooters from the Windows Online Troubleshooting Service" and only use the local troubleshooter file? Moreover, based on my further research, please
make sure there isn't any Group Policy setting blocking the launch of troubleshooters.
First, I recommend you to check the following location in Local Group Policy Editor.
Computer Configuration\Administrative Templates\System\Troubleshooting and
Second, Check these settings and make sure it isn't disabled:
Troubleshooting: Allow users to access and run Troubleshooting Wizards
Troubleshooting: Allow users to access online troubleshooting content on
Microsoft servers from the Troubleshooting Control Panel (via the Windows
Online Troubleshooting Service - WOTS)
Third, you may also check the related registries (both keys are 0x00000001
by default): HKLM\SOFTWARE\Policies\Microsoft\Windows\ScriptedDiagnostics!EnableDiagnostics
Fourth, please verity the Startup type of Diagnostic Policy Service is
Automatic, the Startup type of Diagnostic Service Host and Diagnostic System
Host is Manual.
Ifthe issue persists, I recommend you to test the issue in
Clean Boot Mode.
