"Why the keyboard doesn’t work on my Mac book pro 2018: Suddenly my keyboard no longer works, I don't know why, sometimes it works, but if the device has been working for a long time then the keyboard does not work. But now it doesn't work at all! what is the solution in this case ?"

Clear the Cache:

Boot in Safe Mode:

It seems to me that the caches may be in a loop, and caches keep settings where they once were. So, try booting in to Safe Mode. In Safe Mode, Login Items do not open at login; certain preferences are set aside; and damaged system files (i.e. caches) are fixed. 

1. Boot into: Safe Mode [Hold Down the shift key upon boot].
2. Log in: as same user
3. Wait: 30 seconds
4. Restart: the Mac
5. Boot Up: normally
6. Log in: as same user

Use an External Keyboard:

Sometimes changes (i.e. updates) are made to the system and then settings (i.e. for keyboard) become manipulated, technically.  So, reset both the SMC and NVRAM on your Mac. As for connecting it, you may need this adapter, if the keyboard has not USB-C plug in it USB-C to USB Adapter - Apple

Contact Apple support (link is in upper right corner of this page) and start a repair ticket.

Does the device appear to have an uneven bulge/bottom or is wobbly?
