can’t open network preferences

Hi,

I own a MacBook Air 13” 2015, and for a while now I’ve been having network issues. Before, I would have to remove Wi-fi from my interfaces, restart and readd it just to get it to work. Now I can’t even open network preferences and I am not connected to any network at all (will have a pop up that says “preferences error, there was an error in network preferences”)

I’ve looked through another thread on here with the same issue, but the answers it received haven’t worked. I just want to reinstall MacOS but I obviously can’t do that without internet access, which I do not have. I have tried restarting in safe mode, I have tried removing and re-adding preferences in the system configuration folder, but none of this has worked.
