Hi Derek, My name is Estrella, and I'm a Microsoft user like you. I'm sorry to hear you're experiencing this issue. I'll be more than happy to help.
Please check if Mouse Keys is turned on. If it is, turn it off.
Go to Windows Settings > Select 'Ease of Access' or 'Accessibility'.
In the left menu, find and click 'Mouse' (or 'Keyboard').
Make sure 'Mouse Keys' is turned off.
