Unable to expand environment variable in host setting: 'https://rinkeby.infura.io/v3/$WEB3_INFURA_PROJECT_ID'

Anyone know the cause of this?

Hello @GhoulZoid it means is not finding the project id on your env variables, so please remember to export it from the .env again, as you are on windows try adding it using the advanced configuration on windows.
