Hello I am having a similar issue. I have the following message:

Sketch uses 1882 bytes (5%) of program storage space. Maximum is 32256 bytes.

Problem uploading to board. See https://support.arduino.cc/hc/en-us/sections/360003198300 for suggestions.
This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.
I only have one COM its COM3
Any suggestions?
