These problems can appear after a Windows update, a Skype update, or changes to system settings.

In most cases, Skype not working in Windows 11 is caused by corrupted app data, outdated versions, incorrect permissions, network problems, or conflicts with Windows services. The issue is usually software-related and can be fixed without reinstalling Windows or changing hardware.
