City Engine error

[MatildeSantos]

I went to open my city engine project, but the data that had been created did not appear and the error appeared: "could not load file". What could have triggered this?

Hello @MatildeSantos 

Thank you for posting this question.
Please check if your project data is existing in the defined location on your operating system:

Projects—ArcGIS CityEngine Resources | Documentation

[MatildeSantos]

this is what appears to me in the project window
it should be noted that, from one day to the next, this happened without me doing anything or changing file locations.

Thanks for providing that additional information. Please try the following:

1. delete your project from the workspace (Right Mouse Click on project folder > Delete)
   
2. Import the project again. Menu > Import... > Project > Existing Projects into Workspace

I did what you suggested and the project opened, but it did not generate the models that had already been made...
