struggles connecting to wifi 2016 MBP (networksetup error -3912)

[ihaveawindows]

Hello, I own a 2016 MacBook pro and I've made a thread before, but it didn't get any responses. I am making a new one because I tried connecting via networksetup and it returned with error -3912.

Anyone knows how to fix it?

Error: -3912 The operation couldn't be completed. (com.apple.wifi.apple80211API.error error -3912.)
