Suddenly one of my USB-C ports doesn't charge when I plug in the charger.

It's a Macbook Pro 2020 M1

Did you try rebooting the Machine?

Log out, sleep, wake, restart or shut down your Mac

Shut down or restart your Mac - Apple Support

if no resolve—

No SMC or NVRAM on the M1 SoC.

The best you can do if you have an issue— equivalent Shut down, close the lid 30 secs+ , reboot as normal.

If no resolve try SafeBoot How to use safe mode on your Mac - Apple Support to sort anomalies.

If restarting the laptop as @leroydouglas suggests does not help and only one USB-C port has this issue, then you will need to have Apple or an Apple Authorized Service Provider examine the laptop to provide you with a repair estimate.
