Disappearing images

I’ve inserted around 10 images in my project. Every time I close and reopen the project, the images completely disappear. This has happened several times. Everything else is still there, but not the images :frowning:

What method did you use to import the images? (e.g. Drag and drop, Insert > Image From File…, Insert > Image Linked to File… etc.). If you try a different import method, does that change anything?
