Do a system restore to the last known working config.
If you have Cortana (the search feature lower left of the task bar), type in system restore & it will be at the top of the list as (Create a restore point), click & follow prompts.
Or the path is:
For W10 right click windows button on Task bar lower left, select System (left click).
Now left click System protection in the left list.
Left click system restore & follow the prompts.
If that doesn't fix it you may need to do a windows refresh, I’ll guide you to that if you need it.
