USB-C port issue in Macbook M1?

Sometimes the port responds and sometimes it doesn't. Happening for both the usb-c ports. Ran a diagnostic which said error code PPP020, and PPP001. Anyone faced a similar issue?

MacBook Air (M1, 2020)

PPP001 means a power adapter issue was detected.


PPP020 means no power adapter was detected.


Apple Diagnostics reference codes - Apple Support


Try a different power adapter and different cable, and failing that then contact Apple Support.
