Windows 10: Alt keys not working on windows pc

So this just started this morning when I tried to alt tab.. and the alt button just doesn't work. The tab button still works fine but alt doesn't work, I have a left alt button to the left of the spacebar and I also have a button called alt gr to the right of the spacebar, neither do anything though I'm not sure what alt gr is and if they're connected. I've tried reinstalling keyboard drivers, I've cleaned under the keys. I've used keyboard tester and it doesn't light up at all when I press either alt button. My keyboard is a bluetooth hp keyboard, I don't have a spare usb keyboard to test on

ALT keys not working after developers update

Hello Paul,

To help us identify the cause of this problem, we would like to know the following information:

• Which type of Windows device are you currently using? (PC, tablet or laptop)

• If your device has 2 Alt button, does it happen on both Alt keys on the keyboard?
• Since you're trying to input a special character using Alt key, have you checked if the Num Lock key is activated?

In the meantime, we recommend that you check if Sticky Keys is turned on in the Accessibility settings. Sticky Keys lets you press one key at a time for keyboard shortcuts. To check, refer to the steps below:

• Click on Start.
• Click on the gear icon to open the Settings.
• Click on Ease of Access.
• On the left panel, click on Keyboard.
• Turn off Sticky Keys.
