@monika1111 can you double check if:

1. removing yarn.lock and package-lock.json 
2. rm -rf node_modules && npm install

solve the issue?

Thank you for your quick response.
I have done as you said, but now I got another issue https://prnt.sc/v3st3g, That seems to be because of style-loader version.
When I wanted to change it npm install style-loader@1.0.0 got an error about ckeditor-duplicated-modules.

Hi @monika1111, as I can see you use Craco in your project. Currently, building the editor from the source can be done after ejecting the project and modifying the Webpack config. Unfortunately, we didn't test it with Craco, so it might behave unpredictably. However, there's some community solution for Craco project, which might be helpful in your case, see it here.

We're aware that requiring ejecting a project might not be the best experience and this problem will be covered in this issue.

Now I don't get any error, I have used this article to use craco. https://medium.com/@adamerose/using-ckeditor-5-in-create-react-app-without-ejecting-cc24ffb3fd9c Thanks for your support👍
