Latest version of nrfutil.exe does not run on windows 10?

[RVM]

I am trying to 'reinstall' the nrfutil tools on a Windows 10 desktop where the tool has been working since early 2025. 

I downloaded the latest 'nrfutil.exe' from this Nordic website https://www.nordicsemi.com/Products/Development-tools/nRF-Util/Download#infotabs  and placed it in the folder C:\nrfutils\bin.
I then added this folder to the PATH environment variable.
I also removed the '.nrfutil' folder under my HOME folder i.e. C:\Users\<username>\

Just to be sure and play it safe, I even rebooted my desktop.
Then I launch a DOS CMD window and type the command 'nrfutil'.

What I am seeing is that the command does not terminate and I am forced to kill it with a Ctrl-C. 
Even then the task manager shows a heavy load on the CPU, and it only goes down AFTER I forcefully close the DOS command window. 

Any ideas or will I be forced to upgrade my desktop to a Windows 11?

Must be something on your system, freshly downloaded .exe runs here in a win10 install. Exe is signed by Nordic ASA, so I think you would get an error message if the download was corrupted somehow.

It does take a few seconds to execute here on the though, and its possible that your virus scanner goes haywire.

I ended up reinstalling Windows 10 and nrfutil now works. I believe that it may have been due to my attempting to execute a BASH script meant to be executed on a Mac.
