@Mipmini  Please delete the folder for this pack and reinstall it.  The folder is EP55, and you want the folder directly inside [install location]\The Sims 4, with the install location being wherever you told the EA App to install the game.  You can see it in the App game library, under Sims 4 > Manage > View properties.

You'll need to close the EA App and kill the EABackgroundService in the Task Manager in order to delete the folder.
