I solved my issue.

I ditch Avast antivirus and return with Windows Defender. I also disable any Hyper-V services. no more np1013 error.

Since tuesday, I keep getting that NP1013 error. I don't know how to make it stop. It's so annoying!

I reinstalled the game on Steam which I have to redownload all these crazy 70 GB size and yet, I still have that NP1013 error.

I disabled my anti-virus and it still occurs. I have no idea what cause the NP1013 error. (And no, I don't have that netlimiter software like other Google results I found)

I'm playing the game with Steam.
