My serial monitor does not display anything - Arduino 2.0.3

There is a slightly different question from @eileenchia5 in this discussion:

Why is my arduino code uploading for so long

[image] I try to upload my code to Arduino UNO. It used to work but now it is just stuck on the uploading.

But i'm not sure if it's the same issue - i.e. "stuck on uploading" or a new one.
