Bulk Swap File Names

Is there an easy way to bulk swap the file names of two files in Windows?
Example of what I want: Example: I have fileA.txt and fileB.txt. After the operation, fileA.txt is now called fileB.txt, and vice versa.
This article has some solutions, but I want to do it in bulk, like randomly swap a bunch of filenames in a folder. Easily swap file names?

This program ALSO does it, but I’ve never been able to make it work: https://drive.google.com/file/d/1D8cCI4aXuIZkQGsIMPDRXnB-Ys6iwYdw/view

Any help would be appreciated!
(FYI I use a mac, but I use a Windows VM with Vmware fusion)
