It looks like you’re running in WSL on Windows, you’ll need to store your projects in the WSL file system itself eg ~/ic-projects/, not on the mounted windows drives (which causes file permission issues). Once the replica’s running properly the connection refused error in the second terminal should be resolved too.
More tips for using WSL are in this thread here, if they’re useful: https://forum.dfinity.org/t/native-windows-support/1241/2?u=ori
