pgAdmin does not start

I'm emailing this list because I found in the archives that someone else 
had what seems to be a similar problem 
(https://www.postgresql.org/message-id/CAPF6%3DbvaDA6bvjuh4xO-2yA2LDcuBNhvKx3ZxRBEEWbYn8mUmw@mail.gmail.com), 
but I can't follow all the steps to his solution and I'm not sure 
whether it's going to be the same for me.

I just installed PostgreSQL 11.2 with pgAdmin 4 onto my Windows 10 
system with the intention of using it with Python. Everything seemed to 
go smoothly and in accordance with the video lessons that I am following 
online, but when I went to open pgAdmin 4 it would not load for me. I 
see the splash screen come up, but nothing ever starts and I can't even 
see a process appear in the Task Manager. I'm afraid that my usual 
development environment is Linux, so I'm a bit out of my element and may 
need a bit of extra guidance to find the normal debugging tools and 
system logs. Can anyone give advice as to how I might resolve this? Thanks!
