The answer provided is much straightforward, the right place for the argument is a good thing to know.

BUT it may have escaped its author that Neofetch is originally a Linux Shell program. Therefore it is most often ran through Git Bash, emulating a Linux terminal via Powershell. I have noticed what the original inquirer is pointing at myself, because I couldn't launch Neofetch at first; succeeding only once I had noticed Git Bash program had a shortcut created in the Windows Start menu. Typing and runing Neofetch from there became the easiest thing, and lead me into typing "git bash neofetch" directly within Powershell terminal.

Which is why people would like to provide arguments: ran from Powershell, Neofetch runs unhindered, but its MINGW64 terminal window colapses itself rightafter.

Several answers can be found browsing the net; none of which did work in my case so far. If Git Bash program's course can be changed by specifying arguments, that's how the Neofetch program can be kept windowed.

Although the original message doesn't mention Git Bash, its mentioning of scoop package manager let me suppose there was some misunderstanding, provided Git Bash can aslo be downloaded & installed in a standalone version, the same goes for Neofetch, originally a Linux program. Its belonging with scoop fetch program capacities being according to me only due haphazard circumstancies, ie: shell environment associated programs.
