Problems with Sage installation on macos

Question

I'm running WP on my local MacOS using MAMP. Have installed Bedrock and ran the WP installation, and all is running as expected - my website opening on localhost:3000.

The problem starts when I try to access the site after installed Sage. I am receiving Error occurred while trying to proxy: localhost:3000/ and I have no idea why I am getting this. The moment I stop Sage, MAMP delivers the site. If I try to run Sage again, the error returns.

Just to make it clear, so I'll won't be doing some crazy mistake -

1. I have installed Bedrock.
2. Have installed Sage as a theme.
3. Mamp is pointing to Bedrock's folder, and website's port is configured inside Sage's bug.config.js Any idea what can I be missing?

npm: 9.8.1, node: v16.20.2/v18.17.1 (tried both versions).

Steps I did to understand whats going wrong:

• Have gave Full Disk Access to /sbin/nfsd (reference).
• Have disabled MacOS firewall

BTW- I was looking at the package.json file, and I have seen that Sage appears, inside the devDependencies, as version 6.12.12. Its the latest version from the git repo. Is this means that I am using sage's version 6?
