Just a few days ago I had no problem running the Arduino editor with my chromebook but all of a sudden the past two days every time I try to upload to my Sparkfun Inventors Kit redboard I keep getting this error. Can anyone help? Sending 3020: receiveData timeout after 400ms

3020 timeout after 400ms

How is this still such a big issue?
Running into it with an Arduino UNO here...
