Had the exact same problem and tried the same fixes. The only difference was I knew it worked when it wasn't on a bread board and it stopped working when I plugged it into an empty bread board. That made me think it was a floating pin issue. I moved a jumper around from ground to different pins and somehow it works if you ground out pin A10. (It also seems to work if you pull it to 5v). I don't know why this happens but I can replicate it over and over.
Thanks for your guidance, you just hit the point. It Works!!

Hope this advice can be spread to every beginner, like me, that stumbles into the same problem in uploading for the first time with Blackpill
