Keyboard problem in lock screen

Question

When in the lock screen, sometimes I'm unable to type the specific letter "p".
I tried using the digital keyboard too, but the letter still doesn't show up. It doesn't happen with any other letter, just "p". It is part of my password, so I ended up waiting for 30 minutes until I was able to type again. Is there a reason why that might have happened? I checked the physical key and it didn't seem to have any problems.

Test if the issue occurs in Safe Mode.

Use Ctrl+Alt+Del to get to an alternate login screen

Ensure your system is up to date:

Settings > Update & Security > Windows Update.

Is the "p" key working normally once you're logged in?

If the problem persists, you might want to check the Windows Event Viewer for any keyboard-related errors around the time this occurs.
