Hello @Joffin and welcome to the ST Community 😊.
This error means that the project Can be initiated since it may need a Cube Package (for example STM32CubeH7 if you are using an STM32H7 Mcu) is not installed or updated. So, it will be a good idea to check the firmware updater and download the last version to garantie that it will work.
Best Regards.
