Number key 1 doesn't work on my macbook M1

Hi,

My key number 1 doesn't work, even I try on keyboard viewer, but I can still use that number key like a shortcut or i can use it in lockscreen to type password. I checked my macos is up to date, the mouse keys, sticky/ slow keys are off, my keyboard layout is U.S., reset "keyboard" in the activity monitor, even reset my mac many times.

MacBook Pro 13″

1. Check for Updates

Ensure your macOS is up to date:

Go to System Preferences > Software Update and install any available updates.

2. Reset PRAM/NVRAM

Resetting the parameter RAM (PRAM) or non-volatile RAM (NVRAM) can sometimes fix keyboard issues:

Shut down your Mac.
Turn it on and immediately press and hold the Option + Command + P + R keys for about 20 seconds.
Release the keys and let your Mac restart.

3. Reset SMC (System Management Controller)

The SMC can be reset on Intel-based Macs and sometimes resolves keyboard issues:

Shut down your Mac.
For MacBooks with a non-removable battery, press and hold Shift + Control + Option on the left side and the power button for 10 seconds, then release all keys and power on your Mac.
For desktops and MacBooks with removable batteries, follow the specific instructions for your model here.

4. Check Keyboard Layout

Ensure the correct keyboard layout is selected:

Go to System Preferences > Keyboard > Input Sources.
Verify that the correct keyboard layout is selected. Add the U.S. layout if it isn't there.

5. Accessibility Settings

Check if any accessibility features might be interfering:

Go to System Preferences > Accessibility > Keyboard.
Ensure features like "Sticky Keys" or "Slow Keys" are turned off.

6. Safe Mode

Booting into Safe Mode can help diagnose if the issue is caused by third-party software:

Shut down your Mac.
Turn it on and immediately press and hold the Shift key until the login screen appears.
Log in and test the key in Safe Mode. If it works, the issue might be caused by a third-party application or extension.
