I can confirm that downgrading to "webpack": "^4.45.0" works

[ghost]

It can be resolved with the following commands npm uninstall sass-loader npm install sass-loader@^10.1.1 --save-dev If the version of webpack is 5 then downgrade to any version between 4 and 5 npm uninstall webpack npm install webpack@^4.0.0 --save-dev
