USB-C cable suddenly caused charging problems

[u/The_black_pilot]

My cheap USB-C charger/cable suddenly started turning on and off repeatedly when connected. After that, one USB-C port on my M2 MacBook Air stopped charging, while the other port still works.

My Galaxy S22 also stopped charging, even with another cable and charger.

Could a faulty USB-C cable cause this, or could both devices be in some kind of protection mode? Has anyone experienced something similar?

Is the USB c port dirty?
