Windows version unable to parse localhost

Windows Version 7.0.9 still unable to parse localhost API’s

I would like to retire the chrome version of Postman, but the Windows version is unable to parse the json request, this has been the same issue for several years now, with no resolution. please see below:

Top Screenshot of Chrome-Based Postman (works)
Bottom Screenshot of Windows Postman (same endpoint) DOES NOT WORK

Can we get a resolution on this, or is there some technical limitation to the product which is preventing Postman to behave the same?.
