How to fix a completely unresponsive MacBook Pro 2018 keyboard?

I have a 2018 Macbook Pro 13” with Touch Bar running MacOS Catalina. Today my keyboard suddenly stopped working after sleep. It simply would not output ANYTHING. I foolishly restarted my computer before even trying to look into some settings. After that I was unable to login, connect a bluetooth keyboard, nothing. I could not even hold the option key to boot into bootcamp. I’m simply in shock right now, as my MacBook really cost a ton and is extremely vital to my studies and hobbies. Thank you so much for any help!

It's worth taking it to the Apple Store. There have been hardware/manufacturing problems with recent MacBook keyboards, and if it is such a problem, then Apple should fix it free.

Apple currently has a "Keyboard Service Program" for a range of laptops, including yours.
