I have been testing Backstage and all was going well till I did a yarn install this afternoon and now the whole thing has died on me :)
Whenever I try to run yarn dev it errors out with
[0] Loaded config from app-config.yaml

I cannot see how this is now an issue when this file has been present since I started my work.
even going and doing npx @backstage/create-app@latest in a new folder comes up with the same error....
Any advice much appreciated.
I also ran into this issue today, a version upgrade of Backstage fixed it:
yarn backstage-cli versions:bump
