Hi @FrancisRumsky

It appears to be a hardware issue with the keyboard, as uninstalling and reinstalling the keyboard driver and restarting the device did not resolve the issue. Here are some steps you can try:

1. Check if the keys are physically stuck or obstructed, and remove any debris if present.
2. Try an external keyboard to determine if the issue is with the laptop or the keyboard itself.
3. If the issue persists, try to replace the keyboard.

It's possible that the keyboard layout could have been changed accidentally, resulting in the keys not working as expected. Here are the steps to check if the keyboard layout has been changed:

1. Open Control Panel
2. Go to "Clock, Language, and Region"
3. Click on "Language"
4. Click on "Advanced settings."
5. Go to "Overriding for default input method."
6. Ensure that the correct keyboard layout is selected

If the keyboard layout has been changed, you can select the correct format and see if that resolves the issue with the Ctrl keys.If the laptop is still under warranty, it would be best to contact Acer customer support and request a repair or replacement of the keyboard. If the computer is no longer under contract, you may need a repair shop or a professional to replace the keyboard.

Thanks
