The Touch Bar of my Mac m1 is black, I cannot touch it with the Touch Bar.

If Safe Boot and a restart does not resolve your issue I would suspect a hardware issue:

What mac, OS version? What applications? Is it always black regardless?

Did you try restart?

Restart in Safe Mode. Any change? Restart normally again. Any change?

Login to the guest account. Does the touchbar work there?
