rails new command dies with a strange error

I created a simple "hello world" rails app according to a tutorial I found
online. everything went ok.

Today I want to create a simple rails blog app. So I installed sqlite3
database. Now when I run the rails command to create the directory
structure for the new app it fails ( I have tried this both with and
without specifying the rails version number and the result is the same
error).

I am running windows 10
rails version = 5.2.3
ruby version = ruby 2.6.0p0 (2018-12-25 revision 66547) [x64-mingw32]

The error trace is as follows:

According to the end of the error trace it would seem it is attempting to
create a directory named "C:". Why would it do that ?

Any ideas to how I can fix this error ?

Thanks.

Feeling frustrated, I rebooted my windows 10 laptop and went for a walk.
After I got back and once again tried the "rails new" command, it worked !!!

Curious as to why a simple reboot fixed the issue !!
