When trying to create a new project with the NUCLEO-G474RE board I regularly get the error in the attached image. The project then consists of only the .ioc file and Cube crashes when trying to generate code.
Note that I have no issues creating a project for the NUCLEO-L496ZG board for example.
As a shortcut, you can open the project's file and double click on the .cproject file. If the file association is correct, the workspace should be loaded immediately.
