Hi, good day!
It sounds like the issue goes beyond a single application and may involve Windows itself or the drive where it's installed.
To help narrow down the cause, could you let me know
- Which version of Windows are you using (Windows 10 or Windows 11)?
- Did the problem start after a Windows update, a power outage, or any other specific event?
- Are you able to open File Explorer, Settings, or Task Manager, or do those also fail to open?
- Do you see any error messages when you try to open an application?
I look forward to your update and am willing to collaborate with you until we resolve the issue. Keep me posted by clicking "Add comments" below.
