UPDATE: FIXED
The error description starts with:
...
Failed to pull the backend.
Unexpected token 'export'
C:========================\src\aws-exports.js:36
export default awsmobile;
^^^^^^
SyntaxError: Unexpected token 'export'
...
The problem could be, the app is looking for aws-exports.TS, instead of the JS version
Changed it worked for me.
Update2: After re-installing AmplifyCLI, it works again
