Microsoft Office may not be open after restoring Windows 11

If you want to roll back Windows 11 2022 update to a earlier time, be aware that many apps might not open in Windows.

Microsoft published KB5023152This error message warns that MSIX Windows Application Format applications may be vulnerable or refuses to open. In simple English, it means that Office, Cortana Notepad Paint, Paint, Terminal and Cortana might display error messages or refuse to launch. Other apps could also be affected.

The gaps are not uniform. Microsoft lists these possible app behaviors:

• Instead of opening the application, an error message is displayed that says “This application cannot been opened”.
• Multiple entries may be included in an application’s Start menu.
• You may not receive an application response when you attempt to start it.
• An I/O error can occur, then the application may become unresponsive, and finally the application crash.
• If you try to launch the app again, it will launch.

The bug is currently only affecting Windows 11 22H2, officially called Windows 11 2022 Update. Microsoft does not claim that it is working on a solution to the problem. This issue is currently putting the company’s developers in a serious situation. Solutions include trying to launch the app again, trying to reinstall the app from the Microsoft Store, and running Windows Update — all of which will be part of any basic troubleshooting.

Ironically, the best solution to app installation problems is to go back to a previous system restore point. Tom’s Hardware has provided this solution. Previous reportNotes and bugs. Microsoft will hopefully solve this problem soon.
