Bedrock & sage combination dev server produces gibberish

I just installed bedrock and then the sage starting theme. Nothing done else. I just installed wordpress and then changed the theme to the sage theme and when I go to the dev server address it produces this gibberish:

When I go to the proxy address, it shows up fine.

This is in my .env:

WP_ENV='development'
WP_HOME='http://localhost:8080'
WP_SITEURL="${WP_HOME}/wp"
WP_PORT='8080'

This is in my bud.config.js:

  app
    .setUrl('http://localhost:3000')
    .setProxyUrl('http://localhost:8080')
    .watch(['resources/views', 'app']);
