Hello, I am Henry and I want to share my insight about this issue.
Based on the symptoms you described, it seems like the system is acting as if the Escape (Esc) key is being continuously pressed. Since the issue persists across different user accounts, this suggests a system-wide cause—likely a connected hardware device or a low-level driver. I recommend unplugging all external devices from your computer, leaving only your primary keyboard and mouse connected. This includes:
- Game controllers (Xbox, PlayStation, joysticks, etc.)
- Drawing tablets
- Webcams
- USB hubs
- External drives
After unplugging them, restart your computer and test the search bar. If the problem is gone, plug the devices back in one at a time (restarting after each) until the issue returns. The last device you connected is the cause.
If the problem continues with only your keyboard and mouse plugged in, one of them could be faulty. If possible, test a different keyboard first, as a stuck Esc key is a likely suspect.
Hope this points you in the right direction for troubleshooting.
