I would do the following. 1. temporarily disable all antivirus and test nimble; 2. if it doesn't solve it and as you say that it doesn't print anything on stdout, record a video of what is done so we have an idea of what appears or doesn't appear. Something in cmd or powershell should happen.
Your situation is very weird, could you give more details about the antivirus and the like that you use and sabotage you?
