Hey there, @MoG 
Did you try the solution that Luke shared above in this thread: Site is live, but sill blank screen (react app) - #21 by luke let us know if this didn’t work for you.
I am facing the same issue, my site is deployed at https://portfoliovj162.netlify.app
However when I open it a blank screen appears, when I went to the console panel I noticed some errors 404.
Here are the images:

,i did not understand what [luke] is saying 
@kkchad Your app loads for me, then crashes with the white screen, showing errors in the developer console:
The repository that you’ve linked to is likely set to private and currently shows as a 404.
