pgAdmin 4 crash on startup - Mailing list pgadmin-support

Hi

I'm having an issue with pgAdmin 4 crashing on startup. Any assistance
in getting it working would be very much appreciated.

== pgAdmin Version ==
It is the version of pgAdmin 4 installed by the EnterpriseDB PostgreSQL
10.1-2-windows-x64 installer. The file properties for the executable say
it is version 2.0.0.0.

== Configure Options ==
Unknown. I am using binaries from the EnterpriseDB installer.

== Operating System ==
I'm running on Windows 7 Ultimate (Build 7601: Service Pack 1) 64-bit,
and I am connected to it over a remote desktop connection.

== Server or Desktop Mode ==
I am starting it from the Windows start menu as installed by the
installer. I assume that this would be desktop mode.

== Qt Version ==
The properties of QtGui.dll say it is version 5.9.1.0.

== Python Version ==
The properties of python27.dll say it is version 2.7.11150.1013. I also
have Python 2.7.12 in my Windows path.

== pip freeze ==
C:\Program Files\PostgreSQL\10\pgAdmin 4\bin>pip freeze
Pygments==2.2.0

== Steps to Reproduce ==
I launch pgAdmin 4 by clicking on the shortcut in the start menu created
by the installer, or by double clicking on the executable in c:\Program
Files\PostgreSQL\10\pgAdmin 4\bin.

The application runs for a while, and paints some UI: I can see a menu
bar with options File, Object, Tools, and Help. Below that on the left
is a pane titled Browser. To the right is a pane with a Dashboard pane
active. There are also Properties, SQL, Statistics, and Dependencies
tabs, as well as navigation arrows and a close button.

Once this UI appears, Windows displays a message saying "pgAdmin 4
Desktop Runtime has stopped working". The problem details are:

Problem Event Name: APPCRASH
Application Name: pgAdmin4.exe

I believe that this error code corresponds to an Access Violation in
Qt5Gui.dll.
