NBMiner isn’t working

Hi, I was mining normally till an hour ago. I'm getting the "'nbminer' is not recognized as an internal or external command operable program or batch file" error on my CMD.

Thought it was the AV but I don't have one and my Windows Defender have the file and the folder as exceptions and is already fully disabled. So… what's next?

I am really bothered by the fact that the path is pointing to my system32 file while my NBMiner folder is in my desktop. Could this be it?
