I have replaced everything that mentions the port 3000 but it's still keen to listen on port 3000.

[0] Something is already running on port 3000.
[0] npm run react:dev exited with code 0

I tried running npm run dev but it didn't work. I later found a work around where i first run npm run react:dev and then in another powershell window i ran npm run electron:dev

nothing???
