Bitdefender block expo start

Hi,
I just made the last expo update (3.26.2). I launch my project via npm start, everythings is ok, but when i try to make a webpack, Bitdefender kill the process.

Bitdefender message:

C:\ Program Files\nodejs
(Command line parameter: “node” “C:\Users\******\AppData\Roaming\npm\nodes_modules\expo-cli\expo.js” “start”)

Config:
