Two things to add to this thread. I’m on an M1 MBP using UE 5.1.1 and this problem occurs every single time I delete my Intermediate and Saved directories.
To fix it, I have to:
- With the editor closed, move the content directory to somewhere else on the filesystem, as described.
- Open the editor. Obviously the content directory is empty
- Outside of the editor, move the content back into the project content directory.
- Relaunch the editor.
Seems to work.
