Try to install the same version plugins (it work for me) likes:
check ckeditor5-core version fisrt
@ckeditor/ckeditor5-core": "^33.0.0"
I want to add "table" tool, use
npm i @ckeditor/ckeditor5-table@33.0.0"
to get specified version, instead of
npm i @ckeditor/ckeditor5-table
you may get a newer version, which need the second ckeditor5-core package lead to duplicated-modules (now you know which module duplicated)
