Hi,
About 2 months ago I started a project for a robotics competition in my area, and I'm using an Arduino UNO for most of it. Until some couple weeks ago I was able to upload my code normally to the board, but suddenly the IDE was stuck on the upload message. At first, I thought it was my bluetooth adapter driver I installed around the same period, but even after disabling it, I still can't upload code. Then, I tried changing cables, then changing boards, ports, and realized the issue was on a higher level. Here's the error message after turning verbose on:
