[NTG-context] ConTeXt doesn't recognize source on network drive?

[context at vivaldi.net]

Hello,

after I've updated ConTeXt to the latest version, a new problem appeared 
- see the steps:

(Note that "X:" is a network drive mapped as "\\192.168.112.xxx\px" - if 
it was of importance.)

So:

1. "ConTeXt  ver: 2020.05.08 20:46 MKIV beta  fmt: 2020.5.11" should be
