Refused to execute inline script because it violates the following Content Security Policy directive:

I am facing this error suddenly. My project is crushed in dev mode. Please

`Refused to execute inline script because it violates the following Content Security Policy directive: "default-src 'self'". Either the 'unsafe-inline' keyword, a hash ('sha256-d8xVpEfOlXT388lPL445U0wcaE4cweRSVh5BQpm9scE='), or a nonce ('nonce-...') is required to enable inline execution. Note also that 'script-src' was not explicitly set, so 'default-src' is used as a fallback.`

Found This error on cli:
```

No CSS/SCSS/SASS file is loaded.

I have updated all loader and packages. Lots of Google search but nothing happens.

Without CSS or other style application worked as well.

Have you any solve? Please help

Start by inspecting the PostCSS Loader configuration used for src/myStyle.module.css and compare its options with the reported postcss-loader API schema. Reproduce the dev build with that stylesheet; done means CSS/SCSS/SASS loads successfully without the loader validation failure or resulting CSP error.
