I have the same problem, I just upgrade from v4.27 to v4.28.
Refused to execute script from
'http://127.0.0.1:57313/static/vendor/require/require.min.js?ver=42800'
because its MIME type ('text/plain') is not executable, and strict MIME type
checking is enabled.
(index):39 Uncaught ReferenceError: require is not defined at (index):39
