Answer 1

Yesterday I installed on win10 versions: postgresql-9.6.20 , postgresql-10.15, postgresql-11.10
and had exactly the same error as you have on the latest version.
Solution: When installing, when you reach the Select Components window, uncheck
pgAdmin4 and then install everything. Then you go to pgadmin.org and download pgAdmin 4 and install it.

Answer 2

looks like something went wrong.

Answer 3

On the screen, loading pgadmin, this has nothing to do with the DBMS itself.
