Go to Activity Monitor and kill the process Touch Bar agent/ Touch Bar server.

doesnt work? Try restarting normally. Usually that works for most people.

still doesn’t work? You could go to Apple Authorised Service Provider for help.

meanwhile you could get Xcode and click window>show Touch Bar for the moment.
