Thank you for the update. Please try the guidance in the AI Answer first and let me know how it goes.
As an additional check, I suggest testing Windows Search in a clean boot environment to determine whether a third-party startup application or background service is interfering with the Search interface:
- Press Windows + R, enter msconfig and press Enter.
- On the Services tab, select Hide all Microsoft services, then select Disable all.
- On the Startup tab, select Open Task Manager and disable all enabled startup items.
- Restart the computer and test Search in the affected account.
*Disclaimer: A "clean boot" starts Windows with a minimal set of drivers and startup programs. It helps to determine whether a background service is interfering with your game or program and to isolate the cause of a problem.
These steps of "clean boot" might look complicated at first glance. However, to avoid any trouble for you, please follow them in order and step-by-step so that it will help you get back on track.
If Search works during the clean boot, re-enable the disabled items gradually to identify the conflicting application or service.
If the issue persists after completing all the above steps, the current account may be corrupted. In that case, I recommend backing up your important files and moving to the working new user account. Alternatively, you can perform an in-place repair installation of Windows 11 to repair Windows components while keeping your personal files and installed applications.
Please let me know how it goes and I'll happy to assist further.
