Hi Holden
I am Juliet and It's my pleasure to help you today.
How are you? I hope you are doing good.
I know how frustrating this may be for you but I'll do my very best to help you :)
I would suggest we also try to run the Keyboard troubleshooter
Type troubleshoot setting in the Search bar
Click on Additional Troubleshooter
Select Keyboard then Run the troubleshooter
Wait for it to finish the process
I hope it helps! Let me know the results.
Have a nice day ahead and Stay safe always :)
