USB Accessories Disabled warning keeps showing up

My MacBook Air has a message "USB Accessories Disabled. Unplug the accessory using too power to re-enable USB devices" yet there is nothing plugged in. Please help.

I have tried resetting the SMC but still get this message popping up.

Reset SMC (I know that you already did this) by following the directions applicable to your MacBook here ➔ How to Reset SMC. If that does not solve things then-
Reset NVRAM/PRAM by following the directions applicable to your MacBook here ➔ How to Reset NVRAM/PRAM. If that does not solve things then-
Enter ➔ Safe Mode and see if the screen issue still exists in Safe mode. Log out of Safe Mode and then reboot computer. If that does not solve things then-
Finally if none of the above works then you can enter ➔ macOS Recovery Mode and reinstall the macOS and see if that solves it.
